The Dutch Observatory

It was supposed to be cloudy, but when I got up we had clear skies with much better seeing than yesterday.  Today we have 6 Active Regions on the solar disk.  AR2886, 87, 88. 89, 90 and a new region had come around the NE limb AR2891.  This region was the source of the M1 flare.  Both AR2891 and AR2887 have been producing some C-class flares.  Might be interesting to follow to see if we are in for an R2 classified flare.

I had two appointments today.  Got back from the first one just in time to have an imaging session.  Seeing conditions were very bad at times.  Processing had to wait until after my second appointment.  We do have 5 Active regions AR2886, 87, 88, 89, and 90.  Besides an M1 flare from behind the Eastern limb, and the nice proms around the Solar disk, the areas are pretty much quiet.

Clear skies again!  AR2886 remains stable and inactive.  The new region AR2887, which can be seen much better than yesterday, produced a few B-class flares in the last 24 hours of which I caught a B3.4.  Lets see what tomorrow brings.

Clear skies with below average seeing this morning.  Today we have the start of a new rotation CR2250.  AR2886 stays stable and inactive.  However a new region has come around the SE limb.  It was not named yet in the last briefing, but it is expected later today to be names as AR2887.  Its main spot seems to show a nice penumbra in the 540nm image and.  So it seems to be an interesting area worth following.  Full disk images as well as close ups of the two regions.

Clear skies continue with good seeing.  AR2886 is not showing much of activity  and staying pretty much stable.  A few prominences around the disk remain. Full disk images today and close ups of Active Region 2886 in the three wavelengths.

Another day with clear skies and average seeing.  The new region near the SE limb was named AR2886 and is a stable Hsx with very low activity while covering 170 millionths, but the pores from yesterday in the NW quadrant decayed and disappeared.  Some very nice proms are also visible around the disk.  Full disk images and close ups of AR2886.

Clear skies continue for today’s session.  After one spotless day, a new well organized area with an penumbra that is well formed, turned into view at the SE limb. I expect this area to be named later today as AR2886.  In addition a few pores in the western hemisphere, near the center line of the Sun  seem to be interesting to follow (See 540nm full disk image).  Today full disk images and close ups of the new yet unnamed region.

Clear skies with good seeing conditions.  However, the Sun is spotless today.  AR2882 is gone but managed to accumulate a total active region area during the time it was visible of 3370 millionths, which is the third largest so far in Cycle 25, compared to AR2786 which reached 7300 millionths.  Some nice proms are also visible at the western limb.  Today only full disk images in the three wavelengths.

Clear skies with average seeing.  AR2882, while still covering 250 millionths, is quiet and getting ready to follow AR2885 by rotating around the Western limb.  Some nice proms on the SW and the NE limbs.  Full disk images and close ups today.

For today’s session the weather was great, with great seeing.  We have one Active Region left, AR2882, while according to SWPC, AR2883 decayed to a plage this morning.  However, a very nice prominence is visible at the SW limb, which seems to be an extension of the filaments which strech along the edge almost from South. The umbra of the AR2882 seems asymmetric with the penumbra being encroached from the SE and SW.   Today full disk images with close ups of the region and the prom/filaments.
