One of the largest sunspot groups in years slowly rotating towards Earth

Posted on May 8, 2012

May 8, 2012 – SPACE – One of the largest sunspot groups
in years rotated over the sun’s northeastern limb this weekend. With a least four dark cores larger than Earth, AR1476 sprawls more than 100,000 km from end to end, and makes an easy target for
backyard solar telescopes. Indeed, the active region is crackling with impulsive M-class solar flares. Based on the sunspot’s complex ‘beta-gamma’ magnetic field, NOAA forecasters estimate a 75%
chance of more M-flares during the next 24 hours. There is also a 10% chance of powerful X-flares. –Space Weather
