TwitterSunspot groups 1024 developed over the 4th of July weekend, and while it did not create any historically spectacular fireworks, it has been kicking up modest solar flares. After one of the longest sunspot droughts in modern times, solar activity picked up quickly over the weekend.A new group of sunspots developed, and while not dramatic by historic standards, the spots were the most significant in many months.”This is the best sunspot I’ve seen in two years,” observer Michael Buxton of Ocean Beach, Calif., said on Spaceweather.com.Solar activity goes in a roughly 11-year cycle.

October 3rd, 2008 admin In this diagram, the sun’s oblateness has been magnified 10,000 times for easy visibility. The blue curve traces the sun’s shape averaged over a three month period. The black asterisked curve traces a shorter 10-day average. The “wiggles” in the 10-day curve are real, caused by strong magnetic ridges in the vicinity of sunspots.(NASA Goddard Space Flight Center) Scientists using NASA’s RHESSI spacecraft have measured the roundness of the sun with unprecedented precision.
