Broken ceiling again today with mediocre seeing at 4/10.  Solar activity is still Very Low with no flares in the last two days.  Some activity can be seen brewing at the ENE limb where AR2534 and 35 have formed.  Total Active Region Area is at 210 millionths today between the four areas.  Total Sunspot count is up to 6 from yesterday’s 1.  Captured three full disk images and close ups of some of the regions and some Prom activity at the ENE limb around the AR2535 area.

Great clear skies again with seeing at 8-9/10.  Solar activity today is Very Low again with no (C-class) flares in the last two days. In fact there were only three B-class flares in the period.  AR2532 has deteriorated to a level where it is not registered any more.  Today only 1 Active Region with one Sunspot, giving a Wolf number of 11.  Active region size for AR2533 has grown from 60 to 80 millionths and stays an Hsx region on the McIntosh scale.  Today three full disk images in three wavelengths as well as close ups of the regions.

Clear Skies with seeing at 8/10.  Solar activity is Very Low today with no flares in the last two days. The two Active Regions AR2532 and AR2533 are pretty small with 10 and 60 millionths.  Only two regions today with a total Spot count of 2.  Made three full disk images and close ups of the two regions.

This is my 1000th Astronomy Blog on my http://ceastronomy.org/tramakers site.  It has been a while since I started this, but it just keeps going and going…..
This time a special view of AR2529.  A composite of 14 days of activity in H-a of  this Active Region, shown in 10 images. (Click the thumbnail to see the full image)  All the way from when it announced its arrival on April 7th when it became noticeable at the Eastern Limb, to April 20th, when we barely could see the plasma levitation above the region when it was at the Western limb. It has been a while since we had a Region of this size.  AR2422 reached over 800 millionths Last year September 30th and October 1st.  So these 2 weeks have been exciting.

Clear skies for a change (for a little).  Seeing approx. 8/10.  Solar activity today is Very Low with no flares in the last two days.  Now, where AR2529 is gone, the active region total is down to 90 millionths with only 4 spots in two regions. I  did my normal run, but forgot to take  flats, so some Newton rings slipped in again.  Also, I did not break out AR2532 in CaK. Sorry for that.

The Sun 2016-04-20.  Another day with restricted transparency, but a hole just big enough with thin clouds allowed me to run my normal capture targets, with seeing being around 5/10.  I thought that AR2529 would not be visible anymore, but it was still to be seen in both H-a as well as CaK.  Today three full disk images and close ups of AR2529 as well as AR2532. Solar activity is low with only one C-class flare in the last two days and the total active region area stays at 640 millionths between the two regions.

The great transparency is over, today we have thin clouds moving through.  It probably is the last day for me to see AR2529. The Sun’s activity today is Medium with the one M-6.7  flare in AR2529 in the last two days. Total active region area today is 640 millionths of which AR2529’s part was 610.  Two regions today with a total spot count of 8.  I was able to make full disk images as well as close ups of the Region in the three wavelengths.

Following the release of a powerful C5.8 flare on the 16th, this morning AR2529 entered M-Class territory with a 25 minute M6.7 flare right after midnight.  Today’s activity is Medium with 1 C-class and 1 M-class flare in the last two days.  Region area has also increased for AR2529 to 780  millionths again.  The total spot count today is at 15 between the two regions. Today three full disk images as well as close ups of the two regions in various magnifications and wavelengths.

No images for the 16th because of our Anna Ruby Falls Solar event.  However, the last visitors of the event were treated to a C5.8 Flare in AR2529.  Sunday I had the most stable skies this year with 9-10 in seeing and transparency. The Sun’s activity was still Medium with 4 C-class flares in the last two days.  AR2529 is down to 720 millionths and the two other regions measure only 30.  Total spot count today is 21.  So it was time again for the C11, and made a number of captures of AR2529.  The first close up and so far the best image at a FL of 5600 mm is included below. Also shown a full disk image in each of the wavelengths I capture in, as well as close ups of AR2529 and 32.

Clear skies gave way to clouds, but I had time for some reasonable images. Seeing around 5/10 with clouds moving in.  The Sun’s activity is Low with 4 C-class flares in the last 2 days and.  AR2529 does  not seem to grow substantial and is today at 790 millionths.  We have a total of three active regions with a total area of 810 millionths.  The total sunspot count today is 16 of which 14 are in AR2529.  Today I captured three full disk images in the three wavelengths as well as close ups of AR2529.
