High Cirrus clouds and contrails today.  AR2729 is growing, and covers 30 millionths and 6 spots, but has not produced any flares so far.  Just North of it at a latitude of 10 degrees North, I saw a very small area in CaK and Ha, which showed Cycle 25 polarization in the SDO magnetograms.  However at this low latitude it is questionable if it might become a Cycle 25 area. Images today in all three wavelengths as well as close ups of AR2729 in Ha and WL.

Clear skies with good seeing conditions.  The plage from yesterday has developed in a new active region which was named AR2729.  This will bring the 9 day spotless day streak again to a halt.  In addition to the new area, we did observe a small filament near the NE limb.  Today’s images again include, among others, a continuum close up, this time from the new area.

Clear Skies again but the seeing was variable.  Another spotless day with very little activity.  A small plage was developing visible in Ha and CaK, but not in Continuum.  A small prom was also visible at the NW limb.  For the rest a quiet Sun.

A spotless day with very bad seeing conditions.  Solar Activity remains Very Low.  All that remains from AR2728 is a plage in Ha and CaK.  A few good sized prominences  are visible on the NE, SE and NW limbs, however because of the bad seeing, close up captures did not result in presentable images, so the best I could do was to include the proms in the full disk Ha image.

Well, I reached another milestone.  This is my 1500th. post in this blog since I started it in 2008.  I hope I will be able to continue this for a good number of years more!
For this morning’s session the skies were clear and the seeing was good.  However it is a spotless day.  Some small filaments were visible near the S limb and a nice prominence was visible at the SE limb.  For the rest, the Sun is taking a nap.

Clouds cleared just after 11.  Seeing was below average.  AR2727 can still be seen just at the western limb.  Total Active region area is 20 millionths and  two spots.  A small prom is visible as well as a small plage near the Eastern limb.  Other than this the sun is quiet.

Clear skies again with good seeing.  Solar Activity remains Very Low as AR2727 is still very distinctly visible.  It covers 60 millionths and contains 3 spots.  The small region from yesterday is still a bit visible in CaK but I did not see it in Ha or 540nm.  I did capture this area together with few small filaments but could not make it out.  The magnetogram shows that it is/was  a Cycle 25 plage.  Proms were just at the surface level and not distinct.

Clear skies and around freezing at the time of my observations.  But the seeing conditions are good.  AR2727 looks great and in the northern hemisphere another tiny area is visible in CaK as well as in Ha, and has reverse polarity in the magnetogram.  Looking closely in WL I believe to be able to make out a small pore.  Some faint filaments close to the S limb and small and faint proms at the SE, NW and Western limb. Activity remains Very Los with no flares in the last few days.

Finally clear skies, but the seeing conditions were terrible.  A new active region has popped up yesterday but I had a lot of trouble imaging and processing it because of the seeing conditions, so the result lets much be desired.  A few small filaments were visible at the NE and SW limbs as well as some small proms at the SE and NW limbs.

Clear Skies with below average seeing. The weak area from yesterday has increased and is nicely visible in Ha and CaK, however I did not see it in 540nm at the time of my observation.  When I checked the Big Bear Observatory’s report, which is one of the reporting facilities for SWPC, they did not report it either. Although it seems that a pore or spot started to form, visible in WL,  shortly after my observation.  Will see if it shows up on SWPC’s SRS report for today. In addition, a few prominences were visible at the NE, NW and SW limbs. We now have reached the same number of spotless days (24) in the current streak as the previous highest streak, which ended July 21st.
