AR2736 development

AR2736 has developed rapidly, unusual, since we haven’t seen a decent sunspot for a while.

“Spaceweather” says:

“A few days ago, sunspot AR2736 didn’t exist. Now, the rapidly-growing active region stretches across more than 100,000 km of the solar surface and contains multiple dark cores larger than Earth. Moreover, it has a complicated magnetic field that is crackling with C-class solar flares.”

The images are fairly poor due to the extreme acute angle with the double glazing!

According to “Spaceweather”:

“New sunspot AR2736 is growing rapidly in the sun’s northern hemisphere. This morning at 1118 UT, it announced itself with a C4-class solar flare.” 

Here is a fade animation of the AR2735 / AR2736 spot group pre and post this morning’s flare. The earlier image was at 09:38 UT taken with light cloud cover, the later one at 11:40 UT.
