The Dutch Observatory

Clear and stable skies this morning.  It has been a while since I observed the Sun last. Since yesterday we have two named Active Regions, AR2719 and 20. It has been two months since we had two Active Regions at the same day on the Sun, AR2713 and AR2715!  However the size of the latter two outdid the total active region for today which is at 110 millionths with 11 spots. The Solar Activity remains Very Low with no flares in the last two days.  However, we also can observe a very nice filament and a Prom at the NE limb.

Clear skies with good seeing.  Solar Activity remains Very Low.  AR2718 is still there but some of the other features visible yesterday are now gone.  The NW Prom visible the last three days, is now turned to the far side, so it looks a lot smaller but we still do see the two nice filaments in the NW and SW.

A thin deck of Cirrus clouds covered the sky today.  Solar Activity remains Very Low.  The unnamed Sunspot now has been named as AR2718 and was the source of an A9.1 flare yesterday. Close ups today show AR2718 and a few filaments, and three prominences. For the rest a quiet Sun. When I was posting the images, I realized that I had mislabeled them as CR2006.  Please note this should be CR2007. When I find time I might go back and correct them.

Clear skies, but still some haze persisted.  Had to increase my exposure time again.  The little area at the Eastern limb from yesterday has developed in a small spot, but has not been named yet.  A few filaments can be observed and the proms from yesterday are still there. Today’s images include the full sized Sun in the three wavelengths, as well as close ups of the mentioned areas.

A haze covered the Sun today with good seeing but limited transparency.  Despite this, I was able to capture a number of interesting areas of the Sun.  Four small filaments could be observed as well as three nice proms.  In addition, a plage near the western limb and a small bright area near the eastern limb. So, despite the low activity and compromised transparency a number of interesting images.  Needless to say that the solar activity was Very Low today.

The sky cleared up and I had time for a late session.  Solar Activity remains Very Low.  The plage in Ha and CaK is still pronounced and we still have the two filaments.  The small SW prom from yesterday has turned further West and now shows a nice prominence.  For the rest a quiet Sun.

Clear Skies with average seeing.  Solar Activity is still Very Low.  No new spots today, so the sun remains very quiet with the two plages and the two filaments.  The prominences have also decreased in size.  The last recorded flare on the Sun was an A1.0 flare on August 3rd. It also could be noted that since June 28th  we had only three days with a very small sunspot.

Low transparency with high cirrus clouds.  Solar Activity remains Very Low.  No new spots and the same plages and faculae as yesterday, even the same prominences all of which have moved a bit west. So today’s images cover the same areas as yesterday and the WL full disk image shows some of the clouds of today. I also added another prom image.  Still a lot of data for spotless day 266.

The session started with bad seeing, so not much detail in the full disk WL image, but got better with time.  The two plages are still visible in Ha and CaK.  Did not see any faculaes, but this was probably due to the seeing conditions.  The filaments are still nice in Ha and a few proms were visible around the disk.  Full disk images as well as closeups of some of the areas in Ha and CaK on this spotless day 265 with Very Low solar activity.

Scattered clouds with average seeing conditions.  Solar Activity remains Ver Low.  Today we see the same plages from yesterday in Ha and CaK, and the faculae in WL are not as distinct.  The small prom at the SW limb still persist. The filaments near the Eastern limb have grown in density as well as size. Today full disk images as well as close ups of the mentioned areas.
