View at EarthSky Community Photos. | We first heard of the new sunspot – labeled AR 2738 – from Dr Ski in the Philippines on April 9. He posted this photo and wrote: “Another cool sunspot has come around the sun’s eastern limb (it really is cool; around 2,000°C cooler than the surrounding surface). Full disk images taken at 26X. Close-up captured at 100X. The whiteish areas near the sunspot are called ‘plage’ (from the French for ‘beach’) and are easily visible through a solar filter.” Thank you, Dr Ski.
Sunspot AR2738 as seen by NASA’s Solar Dynamics Observatory (SDO) on April 10, 2019. View more images from SDO. We saw this image at Spaceweather.com, with the comment: “Sunspot AR2738 is crackling with low-level B-class solar flares.”
