Clear skies, but a number of contrails.  Although the plage is very close to the Western limb, I could not make out any spots in AR2813.  SWPC however did still report at midnight AR2813 showing one spot, but covering a very small area (0).  So today only full disk images and we will be focusing on new areas that might pop up.

Clear skies again with very good seeing.  AR2813 has further decayed and I was only able to see it (as a pore?) in the close ups in WL and CaK.  In Ha it was only visible as a plage.  So while it is rotating towards the Western limb it has decayed and probably will disappear.  Today full disk images as well as close ups of AR2813.

Clear skies with good seeing again today.  AR2813’s trailing spot has decayed, but the leading spot is still nicely visible.  The close up in Ha shows today also some small faint proms near the area at the Western limb.

Clear skies with very good seeing.  The area in yesterday’s images was named this morning AR2813.  The spots remains in today’s images, but shows very little activity.  Full disk images as well as close ups.

Clear skies with good seeing.  Following a spotless streak of 4 spotless days, we have a new active region which popped up this morning and is not yet named.  A new region shows in all the images in the NW quadrant.  At noon UT it was not named yet but we’ll see if it will be named later.  Full disk images as well as close ups of the mentioned area.

Clear skies and much better conditions than yesterday!  The Sun is spotless again.  However, a small filaprom is noticeable at the SW limb in the Ha image.  Today only full disk images in the three wavelengths.

Clear skies, but the cold front is moving in with heavy winds and a “dancing” Sun, especially looking at limb.  The Sun is spotless for two days now, and we logged spotless day 895 since Solar High in Cycle 24.  I wonder when we will reach day 900 :-) . The  faculae and plages of the last Active Regions can still be seen in the closeups.

Finally after 7 days, the skies are clear again.  We only have one remaining Active Region, AR2812.  However, the plage of the old AR2811 is also nicely visible in Ha and CaK.  So today full disk images as well as close ups of the mentioned regions in Ha and CaK and AR2812 in 540nm.

Clear skies with average seeing.  The new area that rotated into view, shown in my CaK image from two days ago, was named yesterday AR2811.  Today another area is rotating in view and it contains a spot larger than the leading spot of AR2811.  I expect this area to be named later today.  Also, SWPC reports that AR2811 showed some B-class flares this morning.

Clear and sunny skies with good seeing this morning during my session at approx. 5 hours after the vernal equinox .  AR2810 has decayed some in the trailing spots but has otherwise not shown any activity.  A new plage is barely visible at the NE limb in CaK, but no indication yet if a spot is associated with the area.  Today full disk images and close ups of the mentioned areas.
