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.

Clear Skies with good transparency and seeing.  Solar Activity remains Very Low.  The spot in AR2717 from two days ago is gone and a nice plage visible in CaK and Ha remains.  In addition, some nice faculaes at the Eastern limb are noticeable in 540nm. Some filaments can also be observed near the NE limb, while a nice prominence shows at the SW limb. An interesting Sun for spotless Day 263.

Finally the clouds opened up a little for my observing session after several days of heavy rains, cloudy skies and tornado warnings.  Solar Activity is Very Low.  The small spot that started to show up three days ago in AR2717 is mostly gone again.  I could not identify the spot today, but a nice plage can be seen in Ha and CaK.  Also noticeable are a few filaments near the NE limb.  Time was too short to chase the few proms at the Eastern limb which can be seen a little in the full disk image.  Today full disk images in three wavelengths and close ups of the mentioned areas.
