Details:
Today on Leap Year 02-29-24, I imaged the Large Sunspot AR3590 from my Manorville NY observatory. This day is added to the calendar in leap years as a corrective measure because the Earth does not orbit the Sun in precisely 365 days. Since about the 15th century, this extra day has been 29 February, but when the Julian calendar was introduced, the leap day was handled differently in two respects. This is a HUGE Sunspot AR3590 on the surface of the Sun right now. A sunspot is an area of cooler temperature than its surroundings that is generally caused by powerful magnetic fields from the interior well up through the surface. They can be the place of strong eruptions of charged particles, solar flares, or coronal mass ejections. The Sun is near the peak of its 11-year cycle of such activity. This spot is so large that it can be seen without magnification through solar glasses and is about 10 times the diameter of the Earth lined up side by side.
Kind Regards To All 🙂
