~Space Weather Update~ Big SunSpot emerging~ [1]
BIG NEW SUNSPOT: A large sunspot group [2] is rotating into view over the sun's northeastern limb. The emergence of this apparently significant active region could herald an increase in solar activity. Solar flare alerts: text [3], phone [4].
"SUPER MOON" TONIGHT: Tonight's full Moon is a perigee moon, as much as 14% bigger and 30% brighter than other full moons of 2012. This is a harmless but beautiful astronomical phenomenon. Enjoy the moonlight! [video [5]] [full story [6]] [Moonshots: #1 [7], #2 [8], #3 [9], #4 [10], #5 [11]]
