The Dutch Observatory

The clouds were gone!!! Seeing conditions were not very good at 6/10.  However good enough for the last images for CR2169,  three full disk images and some close ups.  AR2437 is turning to the backside of the Sun and AR2443 is coming in good view.  Flare activity has been medium with 1 M-class flare and 18 C-class flares in the previous 2 days.  7 Active regions today with 37 spots covering a total of 520 millionths. A very nice levitating prominence which is left from a very nice display earlier in the day at the Western limb.

Had some time, and clear skies for an imaging session. (Seeing 7/10) The Sun’s activity is down again and low. Total spot area went down from 510 to 470 millionths while the sport count went up by 1 to 34. Total flares in the last two days was limited to 1 C-class flare. Today, three full disk images and close ups of AR2439 with a nice prominence, and AR2435.

The sky was more unstable than yesterday resulting in lower seeing (6/10). Three full size disk images again today in the three wavelengths. Flare activity has picked up and is high with 4 M-class flares and 20 C-class flares in the last two days. Total Spot area today is 400 millionths double the one for yesterday and total spot count is 33.

Clear Skies with a relative stable atmosphere. So I brought the C11 out again for close ups. Today the Sun has 4 active regions AR2431, 32, 34 and 35 but spot activity is low with only 8 spots and the total spot area is 200 millionths. Flare activity is medium mainly because of the 1 M-Class flare. Total flares are 1 M and 16 C-class flares in the last two days.

Activity level is still Medium with 3 low level M-Class flares and 16 C-Class flares in the last two days, all but one happening in AR2434.  A new active region is coming around the corner AR2435.  Total Sun spot area on the Sun today is 100 millionths with a spot count of 19.  Today I have a full disk image in three wavelengths as well as a close up of AR2434.

The Sun’s activity today is medium with 10 C-class flares in the last two days.  Total Sunspot area has decreased from 120 to 110 millionths and the total sunspot count now stands at 16 in four active regions.  Today’s images are a Ha and CaK image made in the morning using my equipment, and a full disk image and close up of AR2434 made at a first light imaging session at Covington’s Perimeter College, with their new Coronado 90mm.  I like the results.

Clear and stable skies today 8/10.  The Sun’s activity has gone up a bit to medium and produced 11 C-class flares in the last two days.  4 Active regions AR2431, 32, 33,and 34 with a total spot count of 18.  The total sunspot area has increased to 120 millionths.  Today again the full disk Sun in the three wavelengths as well as a close up of AR2434 in Ha as well as at 540nm.

Weather conditions were not good with variable clouds and seeing at 6/10 during the session.  Solar activity is very low with no flares in the last two days.  Two active regions today, AR2430 and 31 with a total Sunspot area of 50 millionths and sunspot count of 2.  It is getting quiet!  Today full disk images in the three wavelengths I have equipment for as well as a close up of the Eastern limb of the Sun with AR2430 and 31 and a nice prominence.

The Sun 2015-10-07.  Solar activity again very low with no flares to report in the last two days.  Sunspot area has decreased to just 100 millionths and the total spot count today has decreased to 2.  AR2427 which still could be seen a little at the beginning of our outreach session at Heard Mixon Elementary, disappeared from our view later in the session because of the Wilson effect.

The Sun 2015-10-06.  Solar activity today is very low with no flares in the last two days.  Total sunspot area has decreased to just 110 millionths with only 5 spots total on the Sun, in AR2427.  These images in H-a taken during an outreach event at Cousin’s Middle school during a short break.
