A session captured through high clouds and lots of con-trails.  Seeing 6/10.  The Sun managed to release one C-class flare coming from an old region: AR2511, making for Low flare activity.  5 Active regions today with the total active region area at 120, and the sunspot count is at 11.  Not much happening on the Sun today, except a nice prominence at the NE limb.  Today three full disk images and only two close-ups as well as a close up of the prom. At the end of the session the clouds made it impossible to make the Flats to compensate for the Newton rings in the Ha close up.  Sorry for that.

Just finished the observing session before the clouds arrived.  Seeing 8/10.  Solar activity is still Very Low today.  The last flare was on March 4th.  BTW this was only a C-1.1 flare.  Total 5 regions today, covering an area of 140 millionths.  Only one 50 millionths area left (AR2513).  Total spot count is 17.   Today again three full disk images and close ups of the regions 2510 and 13, and 2512,14 and 17.

Clear Skies with Seeing at 8/10.  Solar activity is Very Low today with no flares in the last two days.  Five Active regions with a total area of 180 millionths.  Two areas compete for the largest spot at 50 millionths, AR2513 and AR2514.  Total sunspot count is at 18. Today three full disk images again and close ups in all three wavelengths as noted on the images.

A bright clear sky this morning.  Seeing 9/10.  Solar activity is Low with one flare in the last two days.  Active regions have increased to 7 with a total area of 190 millionths supporting 25 sunspots.  The largest active region 2506  has decayed back to 60 millionths and is a Cso again from an Hsx the day before.  Today three full disk images and close ups of the regions, as indicated on the images, in all wavelengths.

Some clear skies with broken clouds. Seeing 6/10.  The Sun’s activity has increased because of one C-class flare in AR2506 which has in the mean time increased to an Hsx spot on the McIntosh scale.  Even B-class flares have been only 5 in the last two days.  The total Active Region Area is at 150 millionths and the total spot count at 10.  Not much activity.  Three full disk images today and three each in Ha and WL of the regions across the disk, where the Wilson effect is nicely visible in AR2506.

Some clear skies, with mediocre seeing at 5/10.  The Sun’s activity today is Very Low with no flares in the last five days.  5 Regions are visible on our hemisphere with the total region area doubling since yesterday to 220.  The largest area is still AR2506 at 110 millionths, while scaling back on the McIntosh scale to a Cso from a Dso yesterday.  The total sunspot count is up from 6 to 15.  Because of the conditions during the observing session, today only a full disk image in the three wavelength as well as an Ha close up of  AR2506 and AR2510, and 13.
