Sunspot Group AR2781
"Sunspot Group AR 2781"
We have a fine sunspot group on the Sun right now. This thing is crackling with C-class solar flares and is sparkling with less-intense magnetic explosions called "Ellerman Bombs". Ellerman bombs are about one-millionth as powerful as a true solar flare. They are named after Ferdinand Ellerman who studied the tiny blasts in the early 20th century. But note that when it comes to energetic magnetic events on the Sun, "tiny" is relative. A single Ellerman bomb is as large as a typical US state and releases more energy than a hundred thousand atomic bombs!
AR 2781 continues to produce occasional C-Flares as it moves across the southeast quadrant of the Sun. The region gained beta-gamma magnetic status on Friday and will remain a threat for an isolated M-Flare. The next several days will see 2781 in prime position for possible Earth directed eruptions.
Speaking of Earth, two Earths could fit into the circular sunspot with the dark center rightmost in the active region!
