The Sun is quite active today with 6 Active Regions: AR1726,27,28,29,30 and 31 and so far about 6 C class flares up to C7.0 all coming from 1726. Wonder what the next few days are going to bring, however, we have a change in weather in the forecast.

The Sun on 2013-04-23.  Very beautiful with some very tall but skinny prominences.  Also the Active region 2726 and 27 have developed very nice.  Flare activity, altough there are many, still limited to B and C class flares.

It has been a while that we had a close by ISS-Moon Crossing and clear skies.  Last sunday was such a day.  The centerline was 500 mtr north of the International Horse Park Parkway in Conyers, so we setup around 23:00 in the parking lot.  The ISS was relative large at 56.4″ and was only at a distance of 490 km and the transit took only 0.55 sec.  I almost  missed the image, but was able to finish changing the disk designation for the video file one second before the transit took place.

Added my image taken on April 18th.  A very nice Sun with 5 beautiful Active Regions: AR1719,21,22,23,24 and some nice but faint prominences mostly in the Southern half of the Sun.  Flare activity limites to B a d C class flares

Broken skies today with high level clouds travelling continuously through the session.  Had to use Registax 5 in order to stack the captures. Today two very nice active region groups, AR1721,22 and AR1723 and 24 with AR1723 being most active with a B 6.0, C1.5 and a C1.3 flare.  Some small promineneces are also to be seen around the disk today.

Today a clear morning with stable skies.  I have not seen the seeing this good in a long time, and the sun does not hold back with more active regions than we have seen in a long time with 14 B and C class flares, mostly from AR1718.  Included also some closeups of Active Region 1711, because of the great seeing conditions, which has grown over the last days to a large spot.  An interesting Sun again today .
