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.

Broken clouds this morning and some equipment problems made me to have to short cut my session.  Today only WL and Ha images.  AR2810 remains stable and is nicely visible at 200 millionths. A small prom can also be seen at the SE limb.

Clear skies this morning with average seeing.  The region I imaged in the Southern hemisphere in CaK on the 10th, was named AR2809 yesterday morning, but it was short lived as it decayed already to a plage.  AR2808 decayed also a bit in the leading spot, so for most solar activity is Very Low.  Today full disk images and close ups in the three wavelengths.

Clear skies, but the seeing was poor.  Earlier in the day, AR2808 did produce a C1 class flare raising the Solar activity to Low.  Close-up images today of AR2808 and the plage/faculae of AR2807.  I realized during my CaK imaging that some new pores/spots might have evolved, but yet un-named in the plage visible in the SE quadrant.  So only a close-up of this area in CaK.

Clear skies this morning.  AR2806 has decayed to a plage just before it turns to the far-side of the Sun, and AR2807 has reemerged but it is barely visible.  A new area has rotated in view and is visible near the NE limb.  The area was named AR2808 this morning and the Wilson effect is very nicely visible in the 540nm close up image.  Full disk images today as well as close ups of the regions of interest.
