No kidding! April Fools’ Comet

Dominique Dierick uploaded this image of Comet 41P/Tuttle-Giacobini-Kresák to Flickr on March 25, 2017.

Comet 41P/Tuttle-Giacobini-Kresák – first detected in 1858 – will be making the closest flyby of Earth since its discovery on April 1, 2017. It’ll zoom past at a very safe distance of around 13.2 million miles (21.2 million km), or some 50 times the moon’s distance. Amateur astronomers with small telescopes are already watching, and more people will see the comet in the coming days, especially since Slooh plans to turn its telescopes in the Canary Islands the comet’s way. Slooh’s presentation will Friday, March 31, beginning at 8:30 p.m. EDT (that’s April 1 at 00:30 UTC; translate to your time zone).

Space.com said:

The comet’s perihelion point, which is that part of its orbit taking it closest to the sun, lies just outside Earth’s orbit. This year, the perihelion passage occurs April 12, when the comet will be 97.1 million miles (156.3 million km) from the sun.

But because the orbit of the comet nearly parallels the orbit of Earth at this point, there will be a six-day period — from March 29 through April 3 — when Tuttle-Giacobini- Kresák will be very near to its closest point to Earth.

The comet is in the far-northern sky. That’s not good news for Southern Hemisphere stargazers, but Northern Hemisphere stargazers with small telescopes can now see the comet in dark skies for much of the night. That’ll be the case from now until mid-April. The comet is passing in front of the stars of the constellations Ursa Major the Greater Bear (home of the famous Big Dipper asterism) and Draco the Dragon.

The comet is not visible to the unaided eye, but can be spotted with a small telescope or strong binoculars. Chart via Starry Night/ Joe Rao @ Space.com

One orbit of this comet around the sun takes about 5.5 years. But of course early skywatchers with telescopes – who were the first to observe this comet – didn’t know that. Astronomer Horace Tuttle of Harvard College Observatory was the first to observe this comet on May 3, 1858. Professor M. Giacobini at the Nice Observatory in France was the second on June 1, 1907. But it wasn’t until L’ubor Kresák, a Slovak astronomer, picked up the comet while scanning with his giant 25 x 100 binoculars on April 24, 1951 that astronomers began to realize that the comets of 1858, 1907 and 1951 were all the same comet. Comets are named for their discoverers so this one carries all three names: Tuttle-Giacobini-Kresák.

Read the full story of this comet’s history from Joe Rao at Space.com

Truth be told, it’s likely to be an unspectacular comet, but interesting if you’ve never seen one. And, of course, it’ll be exciting to those amateur astronomers who stand outside on these chill spring nights – search for it – and manage to pick it up.

However you manage to see it, enjoy it!

Avid comet photographer Chris Schur uploaded this image on March 24, 2017 and wrote: “Seldom does a bright comet pass right through the bowl of the Big Dipper in Ursa Major. After a close pass to the Owl nebula a few days before, the comet went on through and continues to inspire with its huge teal colored coma and sharp central condensation.” Bright comet? Yes, to an experienced comet observer like Chris. He estimated the comet’s magnitude – or visual brightness – at about 9. That’s much too faint to see with the eye alone.

Bottom line: You need a telescope to see Comet 41P/Tuttle-Giacombini-Kresák, which comes closer to Earth on April 1, 2017 than it has since its discovery. Or view online, via Slooh.

Tomorrow, antivaxers march on Washington, and, boy, are they excited! [Respectful Insolence]

About five weeks ago, I took notice of an event that seems to be getting the antivaccine crankosphere a bit riled up and excited. I’m referring to the so-called “Revolution for Truth” march on Washington being organized by various antivaccine groups, who, emboldened by President Donald Trump’s long, sordid history of expressing antivaccine views, his meeting with antivaccine agitator Andrew Wakefield in secret in August, and his meeting with antivaccine activist Robert F. Kennedy, Jr. in January, really believe that now is their moment and that 2017 will be the antivaccine year. Thanks to, among others, Donald Trump, vaccine policy, which used to be a bastion of bipartisanship, is becoming dangerously politicized, with antivaccine conspiracy theories getting darker and darker. Given that this antivaccine march on Washington will take place tomorrow, I was curious to see what its proponents have been up to as the day nears.

On Sunday, this appeared on the Revolution for Truth Facebook page:

Not surprisingly, the first thing they want their demonstrators (and those who can’t go) to do is to contact the White House and say:

Vaccine injuries are real and devastating. One in 68 children (1 in 42 boys) now has autism. Autism should be declared a national emergency and a higher priority. I support an independent vaccine commission.

This is, of course, typical antivaccine misinformation. Notice the implication that all of this autism is caused by vaccines, when the science is very clear that it is not. I also note that this “independent” vaccine commission that antivaxers want would not truly be “independent. When they say “independent,” they mean a commission run by one of their own, like Robert F. Kennedy, Jr., which could call CDC and FDA witnesses to harass them with questions about vaccines and autism based in pseudoscience. The reason they’re excited about an “independent vaccine commission” is because, after his meeting with then President-Elect Trump, RFK Jr, being RFK Jr., couldn’t help but blab that the then Trump had asked him to chair just such a commission. Hilariously, the transition team quickly slapped him down, saying that no such offer had been made. Unfortunately, damage was done. It was bad enough that Trump would have met with such a die-hard antivaccine crank as RFK Jr. about vaccines and autism, no matter what the reason, and the possibility that Trump might have offered RFK Jr. the chair of an antivaccine commission with the imprimatur of the President on it was an excellent way to undermine confidence in vaccines.

Next up, Revolution for Truth wants antivaxers to contact their Senators and Congressional Representatives to demand that they subpoena CDC scientist William Thompson, a.k.a. the “CDC whistleblower” (at least since 2014, anyway). Thompson, of course, is a rather bitter, clueless man who appears to have had a falling out with his co-authors on one of the seminal papers looking for a correlation between MMR and autism—it didn’t find one—because he believed that the way the report was written up was not sufficiently transparent about how it corrected for confounders in a subgroup where the study found an apparently elevated risk of autism associated with MMR vaccination. The story is too long to go into in much detail, but suffice to say that the association was almost certainly spurious, as it went away with more controls. Thompson apparently nursed a grudge for nearly a decade and, for whatever reason, decided to start unloading on and confiding in Brian Hooker, a biochemical engineer turned antivaxer and incompetent epidemiologist, providing him with the original data to mangle with a “reanalysis” so epically incompetent that a brand new journal actually retracted the paper.

Unfortunately for poor, clueless Dr. Thompson, Hooker recorded their conversations without his knowledge. Even more unfortunately for Thompson, somehow Andrew Wakefield got wind of the existence of those recordings, obtained them from Hooker, and then made a video featuring cherry picked quotes by Thompson venting to Hooker. Basically, the whole thing is, when objectively examined, a big nothingburger. However, because it confirms in antivaxers’ fragile eggshell minds the central conspiracy theory of the antivaccine movement, namely that there’s evidence that vaccines cause autism that is being “covered up” by The Man, the “CDC whistleblower” conspiracy theory had legs. (Not surprisingly, Thompson’s silence since lawyering up two and a half years ago only contributes to the conspiracy theory, with some antivaxers believing that The Man has gotten to Thompson.) While it was fascinating to watch close-up the birth of a new conspiracy theory, dealing with it has become a major headache for pro-science advocates because antivaxers have basically gone wild on social media over it and used it as a rallying point. Meanwhile, Andrew Wakefield and Del Bigtree have made an antivaccine propaganda movie, VAXXED, that has become a rallying point. Not surprisingly, a large part of the movie is about the “CDC whistleblower.”

Since the last time I took note of this attempt to party like it’s 2008, which was the last time there was an “major” antivaccine march on Washington; i.e., the “Green Our Vaccinesmarch, led by Jenny McCarthy and Jim Carrey. Only this time around, the cast of characters is different. Scheduled to speak at “Revolution for Truth” are: Robert F. Kennedy, Jr., Barbara Loe Fisher, Minister Tony Muhammad, Del Bigtree, Brian Hooker, PhD, Paul Thomas, MD, Judy Mikovits, PhD, Toni Bark, MD, Marcella Piper-Terry, Kent Heckenlively, Diane Hennacy Powell, MD, Sheila Lewis Ealey, Jennifer Margulis, PhD, Zen Honeycutt, Robert Moxley, Tami Canal, Sherrie Saunders, Jim Turner, and Alexis Baden-Meyer. We’ve met some of them before, but others we have not. For instance, I had never heard of Alexis Baden-Meyer before, but apparently her primary gig is anti-GMO, if her TruthOut page is any indication. That’s not surprising, as anti-GMO and antivaccine go together like pizza and beer. Of course, in this case the beer and pizza are both crappy. Maybe I should say they go together like cat poop and a litter box. Robert Moxley, on the other hand, appears to be a criminal defense attorney in Wyoming (!) who also does civil litigation regarding—you guessed it!—”vaccine injury.” Sherrie Saunders was a medic in the Army who has now gone antivaccine over her having given anthrax vaccine to soldiers and now thinks that the Gulf War syndrome is—surprise! surprise!—an adverse reaction to the anthrax vaccine due to “animal protein” in the vaccine. Not surprisingly, she’s been interviewed by the VAXXED crew.

Not surprisingly, excitable fellow that he is, Kent Heckenlively is all fired up to go to the rally. Oddly enough, he’s already provided his intended remarks, which to me would mean that his speech would be the perfect time for a bathroom or coffee break. He’s also provided it in all caps, which is even more appropriate. I thought about typing out the excerpt I’m going to provide, because all caps bother me, but then I decided just to copy and paste because (1) all caps is very appropriate for anything Heckenlively writes; (2) I’m lazy; and (3) I was up late last night doing emergency surgery and don’t have a lot of time before I have to leave for work. Get a taste of what attendees will be hearing:

IT WAS A BIT OF A SURPRISE TO FIND THAT THE SAME VILLAINS WHO HAD BEEN RESISTING AN HONEST INVESTIGATION INTO CHRONIC FATIGUE SYNDROME CALLED FOR BY DR. MIKOVITS, WERE THE ONES I HAD KNOWN FOR YEARS WERE RESISTING AN HONEST INVESTIGATION INTO AUTISM CALLED FOR BY DR. ANDY WAKEFIELD.

THAT’S WHY I WROTE THE BOOK, INOCULATED: HOW SCIENCE LOST ITS SOUL IN AUTISM, TO GIVE A BEHIND THE SCENES ACCOUNT OF NOT JUST WHISTLE-BLOWER, DR. WILLIAM THOMPSON’S CLAIM OF CORRUPTION AT THE CDC REGARDING VACCINES AND AUTISM, BUT TO GIVE A WIDER VIEW OF THE AMAZING CAST OF AVENGERS WHO ARE FIGHTING THIS ENORMOUS EVIL. I WANTED TO FOCUS ON DR. BRIAN HOOKER, WHO BEFRIENDED THE WHISTLE-BLOWER, AND IS A LIVING EXAMPLE OF HIS CHRISTIAN FAITH IN HOW HE LOVED THE SINNER WHO WAS DR. WILLIAM THOMPSON, WHILE AT THE SAME TIME HE HATED THE SIN. I WANTED TO HAVE A GOOD DEAL OF SPACE DEVOTED TO DR. ANDY WAKEFIELD, WHO HAS SUFFERED SO GRATLY, BUT TO WHOM WE ALL OWE SO MUCH.

A GREAT DEBT IS OWED TO ROBERT KENNEDY, JR., WHO COULD HAVE HAD A QUIET, PEACEFUL LIFE, TRYING TO GET MERCURY OUT OF FISH, BUT INSTEAD CHOSE TO TRY AND GET MERCURY OUT OF OUR KIDS, AND CALLED DOWN THE WRATH OF THE PHARMACEUTICAL COMPANIES ON HIS HEAD. AND I WANTED TO WELCOME NEW RECRUITS TO THE FOLD, LIKE MINISTER TONY MUHAMMAD FROM THE NATION OF ISLAM, A TRUE WARRIOR AND LION OF THE LORD.

YOU SEE, IT IS NOT SCIENCE WHICH OPPOSES US. IT IS A FEW EVIL AND TWISTED SCIENTISTS WHO HAVE FORGOTTEN THAT SCIENCE IS SUPPOSED TO MAKE THE LIFE OF HUMANITY BETTER, NOT LINE THE POCKETS OF THE PHARMACEUTICAL COMPANIES.

HONEST SCIENCE, SCIENCE WHICH IS IN ACCORD WITH THE PRINICPLES OF HUMANITY, WANTS TO ALLEVIATE SUFFERING. THAT IS THE KIND OF FIRECE DEVOTION I FOUND IN DR. JUDY MIKOVITS. IT IS THE SAME KIND OF DEVOTION WHICH DRIVES DR. ANDY WAKEFIELD. I KNOW THERE ARE OTHER SCIENTISTS OUT THERE WHO CAN YET REDISCOVER THE BETTER ANGELS OF THEIR NATURE AND JOIN OUR CAUSE.

AND SO MY BROTHERS AND SISTERS, I BELIEVE THAT SCIENCE CAN GIVE US THE ANSWERS AS TO HOW TO RESCUE OUR LOST CHILDREN. I THINK OF MY OWN DAUGHTER, JACQUELINE, EIGHTEEN YEARS OLD, WITH WHOM I HAVE NEVER HAD A CONVERSATION. I RAISE MY VOICE AGAINST SOME OF THE GREATEST POWERS IN THE LAND BECAUSE IN DOING SO I HOPE MY EFFORTS WILL ONE DAY HELP HER FIND HER VOICE. IF THAT MAKES ME AN OUTLAW, IF IT MAKES FRIENDS AND FAMILY MEMBERS TURN AWAY FROM ME, IF IT MAKES ME A NON-PERSON IN THE EYES OF THE MEDIA, IF IT MAKES ME A DEPLORABLE, SO BE IT. I WILL WEAR THAT NAME AS A BADGE OF HONOR.

THIS IS A GREAT CAUSE IN WHICH WE FIGHT, PERHAPS THE GREATEST OF OUR TIME. WE FIGHT FOR NOTHING LESS THAN THE SURVIVAL OF HUMANITY.

The “greatest” fight of our time? A fight for “nothing less than the survival of humanity”? It’s just “evil and twisted” scientists who oppose us? (What’s next? Dr. Evil cackling and brandishing a syringe?) I’ll give Heckenlively credit. He sure does know how to exaggerate beyond all reality. I suppose that’s to be expected from someone who likes to fancy himself as the Aragorn facing down the Dark Lord Sauron’s hordes, even though his forces are hopelessly outnumbered, in the fantasy novel and movie The Lord of the Rings. It also fits with the overall tone of the march, which conflates “freedom” with the the ability to leave children unprotected against deadly diseases just because the marchers believe against all evidence that vaccines cause autism.

Meanwhile, Marco Cáceres, declaring the march as one of “few causes more fundamental,” is quick to lower expectations:

The Mar. 31 rally will not involve the big numbers that have been seen at more recent rallies on Capitol Hill but it would be a mistake to misinterpret that fact as truly reflective of the size of the ever increasing numbers of Americans who are becoming enlightened about environmental risks to their health. It is worth noting that a significant number of people who would otherwise be at the event will be at home caring for children and other relatives who have been sickened or injured by the toxins in our environment, foods, and pharmaceutical products.

Anyone who remembers the “Green Our Vaccine” rally knows that it attracted, at most, a few hundred people. The “Revolution for Truth” rally might attract a bit more, given that Donald Trump is in office, but it won’t be particularly big, either. That’s because, even in the age of Donald Trump, the antivaccine movement remains a pathetic group of cranks. Unfortunately, the amount of mischief and harm it causes belies its size.

And then there’s this, from an email on the Revolution for Truth organizing list:

Its going to be raining on Friday 3/31/2017!

As a result of the storm that is expected in Washington D.C. on Friday afternoon, we had to select a new venue for our Rally. Please plan accordingly for possible inclement weather in the morning. We will still meet at Lafayette Park at 9am to march to the Press Club starting at 9:30am.

After the protest at the Press Club, please plan to be at the JW Marriott in plenty of time for the 1:00pm start time to hear the incredible leaders who are joining forces to defend Health Freedom in America!

The current weather forecast appears to show a 90+% chance of rain, along with a thunderstorm. One hates to fall victim to the trap of anthropomorphizing the weather and ascribing causation to correlation, but it’s nonetheless tempting to think that Mother Nature is trying to tell these cranks something.

The Mar. 31 rally will not involve the big numbers that have been seen at more recent rallies on Capitol Hill but it would be a mistake to misinterpret that fact as truly reflective of the size of the ever increasing numbers of Americans who are becoming enlightened about environmental risks to their health. It is worth noting that a significant number of people who would otherwise be at the event will be at home caring for children and other relatives who have been sickened or injured by the toxins in our environment, foods, and pharmaceutical products.

Anyone who remembers the “Green Our Vaccine” rally knows that it attracted, at most, a few hundred people. The “Revolution for Truth” rally might attract a bit more, given that Donald Trump is in office, but it won’t be particularly big, either. That’s because, even in the age of Donald Trump, the antivaccine movement remains a pathetic group of cranks. Unfortunately, the amount of mischief and harm it causes belies its size.

And then there’s this, from an email on the Revolution for Truth organizing list:

Its going to be raining on Friday 3/31/2017!

As a result of the storm that is expected in Washington D.C. on Friday afternoon, we had to select a new venue for our Rally. Please plan accordingly for possible inclement weather in the morning. We will still meet at Lafayette Park at 9am to march to the Press Club starting at 9:30am.

After the protest at the Press Club, please plan to be at the JW Marriott in plenty of time for the 1:00pm start time to hear the incredible leaders who are joining forces to defend Health Freedom in America!

The current weather forecast appears to show a 90+% chance of rain, along with a thunderstorm. One hates to fall victim to the trap of anthropomorphizing the weather and ascribing causation to correlation, but it’s nonetheless tempting to think that Mother Nature is trying to tell these cranks something.

Seahorse aurora

Juan Carlos Casado captured this photo in Saariselkä, Lapland, Finland on March 28, 2017. He wrote: “All night the sky was full of auroras, which sometimes intensified showing colors, movements and striking structures, like this one that reminds of a seahorse. The image was captured with a fisheye lens and a modified Sony A7S camera, which thanks to its high sensitivity allows to take shorter exposures and capture more detail in the auroras.”

Moon and Mars at nightfall March 30

Tonight – March 30, 2017 – look for the waxing crescent moon and red desert world Mars. To view tonight’s evening couple, simply look in your western sky at nightfall and early evening. Keep in mind that Mars will appear no brighter than a modestly-bright star.

On March 30, the lit side of the waxing crescent moon points in the direction of the planet Mercury. If you live in the Northern Hemisphere or the Southern Hemisphere tropics, you might catch this world with the eye alone an hour or so after sunset. If you can’t see Mercury with the unaided eye, try your luck with binoculars.

Mercury won’t be easily visible from southern temperate latitudes, even with binoculars, because it sets so soon after the sun.

Given a clear sky, everyone worldwide should be able to see the bright star Aldebaran and the Pleiades star cluster, the constellation Taurus the Bull’s two most prominent signposts. Over the next several days, watch as the moon travels in front of this backdrop constellation of the zodiac.

Watch for the waxing crescent moon to meet up with Mars on March 30 and the Pleiades star cluster on March 31. The green line depicts the ecliptic – Earth’s orbital plane projected onto the constellations of the zodiac.

By the way … why is Mars faint now? Sometimes it’s as bright as Jupiter (which, by the way, can be seen ascending in the east when true darkness falls). Jupiter is bright because it’s so big, and it’s particularly bright now because it’s about to reach its yearly opposition when Earth goes between it and the sun. That’ll happen on April 7. So Jupiter and Earth are on the same side of the solar system now, nearly at their closest for 2017. Meanwhile, Mars is far across the solar system from Earth now, and that’s why it currently appears so faint. Earth will soon “turn the corner” ahead of Mars in orbit, causing Mars to fall into the sun’s glare.

In any year, you can follow an imaginary arc in the handle of the Big Dipper to the bright stars Arcturus and Spica. This year, 2017, is extra special because the dazzling planet Jupiter beams close to Spica all year long.

Bottom line: Let the moon guide your eye to the red planet Mars (and possibly Mercury) as darkness falls on March 30. Then – after it gets good and dark – turn eastward to see Jupiter rising.

Prevention message opportunities in media coverage of worker fatalities? [The Pump Handle]

From time to time I write a blog post titled “Not an accident.” These posts highlight the name of a recent workplace-fatality victim and also challenge the often-used term “accident” to describe such an event.

The hazards that lead to workers being killed on job—from being pulled into or crushed by machinery to falling from a roof— are well-understood and can be addressed. Yet most worker fatalities are described by police spokespersons as “accidents” and the term is then repeated in local press accounts. Could the press instead communicate how such incidents could be averted?

Several researchers involved in agricultural injury prevention have been exploring that topic. Dr. Barbara Marlenga and colleagues examined 113 news accounts from 2012 to 2014 of farm injuries involving children. They published their results in this month’s issue of the Journal of Agromedicine.

In 79 percent of the accounts, a local law enforcement official was the originating source of the incident information. The news coverage that followed relayed the source and mechanism of the injury (such as tractor and rollover, or animal and pinned) nearly 100 percent of the time. In contrast, less than 8 percent of the time did the news account include a prevention message. In those rare cases, the authors found the prevention messages too general to be useful, such as:

  • “be extremely careful around farm equipment”
  • “stay alert and pay attention”

Marlenga and her colleagues offered examples of messages they consider more instructive:

  • “follow guidelines for age-appropriate work”
  • “no riders in loaded buckets”
  • “institute safe storage practices”

The authors ask and so do I, how would we go about getting news organizations to include prevention messages in their reporting on worker fatalities and serious injuries?

In just the last few days, workers died from traumatic injuries in Cheltenham, PA; Rib Mountain, WI; Milwaukee, WI; Mecklenburg, NC; Maryville, TN; Waltham, MA; Detroit, MI, and other locations. Next week, worker fatalities will occur in different cities. How could one go about outreach to news organizations—outreach that takes place before an incident occurs—to encourage a prevention message be included in news coverage of work-related fatalities.

Or, as Marlenga and her colleagues suggest, should the outreach about prevention messages be directed at law enforcement agencies? They are after all the source of information for a majority of the media reports of the worker fatality incidents.

Then I wonder, if we figured out who could provide the prevention message, could we agree on what that message should be?

In a news account about a worker who fell to his death from a 12 foot ladder, would any of these be an appropriate prevention message?

  • “OSHA requires fall protection for work above 6 feet”
  • “Employers are required to provide fall protection”
  • “Place a ladder on a stable, level surface”
  • “Place a barricade around a ladder to keep equipment or people from moving it”

Does it matter if the prevention message is not necessarily relevant to the circumstances of the incident?

The paper by Marlenga and colleagues, “News reports and their role in child agricultural injury prevention” intrigued me. I appreciate papers that stir up lots of questions.
