X-Class Solar Flare in Progress
Posted by DaveMitsky on Tuesday, January 07, 2014 1:00 PM

I just came back inside to warm up a bit.  (The temperature is 8 degrees F with a real feel temperature of -10 degrees F.)  An X-class solar flare was easily visible in H-alpha light through my 40mm f/10 Coronado PST and an 8-24mm Vixen zoom eyepiece.

AR1944 could be seen readily without magnification through black polymer and Mylar solar eclipse shades.

The Sun is sinking towards southwestern horizon now and the temperature is 7 degrees F (-14 degrees C).  I tried to take some afocal photos of the flare and AR1944, none of which turned out very well. During the course of my observations, I also used 28mm Edmunds RKE, 24mm Explore Scientific 68 degree AFOV, and 10mm Tele Vue Delos eyepieces.  The Delos produced a striking 40x view. 

I didn't see much in the way of prominence activity but there were a number of filaments near AR1944, as well as some smaller sunspots.  

The video posted at http://spaceweather.com/images2014/07jan14/ar1944_anim.gif?PHPSESSID=8vqhethd5998n9ecausduiae12 shows the progress of AR1944 over the past four days.

I just came across more images of AR1944 and the solar flare.
