This is my 1100 st. post in my Blog!  I still remember vividly when I started it many years ago. The sky was clear this morning with better than average seeing.  Today’s Solar Activity is Low with three C-class flares in the last two days.  We have 4 named regions and at some not named yet.  Total Active Region Area today is at 290 millionths with a total spot count of 24.  The prom at the NE limb from yesterday shows today as a very nice filament.  Also two regions at the Eastern limb have not been named yet, but should be today. And while they rotate further West, AR2582 and 83 are ready to turn to the far side of the Sun.  Today full disk images as well as close ups of the regions.

Clear Skies with average seeing.   Solar Activity is still Low with 4 C-class flares.  Total Active Region Area has increased to 350 millionth mainly of the increase of AR2583.  Both AR2581 and 2 are Cso classifies whereas the others are unchanged.  Total spot count today is at 27.  Today full disk images as well as close ups of the areas.  A new plage is visible in Ha as well as CaK at the Eastern limb.  Also note the proms at the Eastern limb.

It took a while for the clouds to break up a little.  Seeing today was average.  Solar Activity has been raised to Low today because of three C-class flares in the last two days in the new region AR2583.  Total Active Region Area today is at 200 millionths for the four regions.  Total spot count is at 24.  AR2581 is a Cao region, AR2582 and 83 are Dao, while AR2580 has decayed to a Crx on the McIntosh scale.  Today full disk images as well as close ups in three wavelengths for the regions.

Broken skies again this morning with average seeing.  Solar Activity is still Very Low with no C-class flares in the last two days.  We have three active regions AR2580, 81 and 82 with a total region area of 130 millionths and a total spot count of 22.  Today I made sure my close ups were focused properly so we have full disk images as well as close ups of the three regions.  A few nice filaments are visible.

Broken skies with below average seeing today.  Solar Activity today is still Very Low with no C-class flares in the last two days. Total Active Region Area today is at 110 millionths and the three regions support 14 sunspots.  I don’t know what happened, but the three close ups in 540nm came out terrible.  Most likely I thought I finished focusing, but during the processing, it turned out the data I captured was unusable.  So today three full disk images and close ups in Ha and CaK only.

I spend some time putting together a composite, showing how the morphology evolved for the two areas AR2565 and AR2567 between July 11th and July 24th, when they were visible for us during Carrington Rotation 2179.  The composition shows the Active Regions as seen filtered in 540nm as well as Ha. The thumbnail is quite fuzzy, so click the full sized icon above the image to see the full resolution image.

Another clear morning with average seeing on the last day of Carrington Rotation 2180.  Solar Activity is still Very Low with no C-class flares in the last two days.  AR2580 as well as AR2581 are picking up in size while AR2579  is getting smaller.  Total active Region Area today is at 120 millionths with a total spot count of 9.  Today’s images include the usual full disk images as well as close ups in the three wavelengths.  Also to note today are some nice small filaments in the Ha images.

Clear skies with great seeing.  Solar activity is Very Low with no flares in the last two days.  We have 3 Active Regions with a total area of 120 millionths and a total spot count of 17.  Full disk images today with close ups of the regions including a not named area.

Cirrus clouds with average seeing.  The Solar Activity remains Very Low with no C-class flares in the last two days.  AR2578 is decaying badly and the two regions on the Eastern half of the hemisphere have been named AR2579 and AR2580.  Total Active Region Area today is 80 millionths with 11 sun spots.  Today full disk images as well as close ups of the regions and the remains of the  old AR2578. My apologies for the Newton rings in the Ha close ups.  I had problems with the flats to correct them.

Seeing was pretty bad this morning with lots of con-trails and high Cirrus clouds.  Solar Activity is still Very Low with no C-class flares in the last two days, although at this time, a new not named region that popped up overnight in the NE quadrant, produced 3 B-class flares so far.  The region that came around from the far side yesterday has not been named yet either.  Today’s images include full disk images in three wavelengths as well as close ups of AR2578 which measures only 10 millionths, and the two not named regions.
