Today the first day of CR2137.  The Sun has been getting very active again.  Yesterday with 9 active regions, today 8.  I had the time for closeups of 1745,  46, 47 and 48.  1748 looks so innocent, but it is producing a number of M and X class flares.

Yesterday I intended to make a few images during an outreach program.  Brought my table but forgot the DMK and missed the huge prominence.  Today brought it and was able to sneak in the time to make one image.  1748 is the region that produces the M class and X class flares. (Left at the rim) Note that the orientation of the Sun today is different thasn my normal orientation (Did not correct for the Alt/Az at the outreach program).

Finally a sunny day and no outreach.  Today the sun was very busy with 10 active regions and some of them showed some nice activity.  AR1744 and 45 are turning nice in view and might develop into something special in the next few days.  Today also a close up of AR1744 and 45 made using the C11 and my 3.8 Baader filter with an additional green filter.

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 .

Not many clouds in the morning, but stability was not good again.  Today only a full disk image with active regions AR1704, 06, 07, 08.
