Sunspot AR1476 takes aim on Earth

Posted on May 11, 2012 by

From Spaceweather.com NOAA forecasters estimate a 75% chance of M-class solar flares and a 20% chance of X-flares during the next 24 hours. Any eruptions are likely to be geoeffective because the source, sunspot AR1476, is directly facing our planet. … Continue reading →
