Big Sunspot Group AR 1339

November 6, 2011 Leave a comment

Sunspot group AR 1339 is an impressive sight right now and its high energy Delta class magnetic field has produced some spectacular M-Class flares over the last 24 hours. As it approaches the central meridian of the sun it is worth keeping a watch for X-Class flares from this region which may produce some impressive auroras down here on Earth. AR1339 appears at the top in the images with AR 1338 below. To the left three new active regions are just rounding the limb (AR’s 1340, 1341 & 1342). Images taken 11.21 – 11.46 UT using a DMK41 camera, CaK PST, Ha PST, CaK B1200 diagonal.
