Meaning, they transit the meridian at the same time (approximately 8:30 p.m. local time). If you reside in mid-northern latitudes … look for the familiar polygon of Corvus at this time. Then extrapolate a line approximately 40° down to get an idea of how far below your horizon the Southern Cross is.” If you’re further south, of course, as Dr Ski is … just look!
