Clear skies with below average seeing this morning.  Today we have the start of a new rotation CR2250.  AR2886 stays stable and inactive.  However a new region has come around the SE limb.  It was not named yet in the last briefing, but it is expected later today to be names as AR2887.  Its main spot seems to show a nice penumbra in the 540nm image and.  So it seems to be an interesting area worth following.  Full disk images as well as close ups of the two regions.

Another day with clear skies and average seeing.  The new region near the SE limb was named AR2886 and is a stable Hsx with very low activity while covering 170 millionths, but the pores from yesterday in the NW quadrant decayed and disappeared.  Some very nice proms are also visible around the disk.  Full disk images and close ups of AR2886.

Clear skies continue for today’s session.  After one spotless day, a new well organized area with an penumbra that is well formed, turned into view at the SE limb. I expect this area to be named later today as AR2886.  In addition a few pores in the western hemisphere, near the center line of the Sun  seem to be interesting to follow (See 540nm full disk image).  Today full disk images and close ups of the new yet unnamed region.

Clear skies with good seeing conditions.  However, the Sun is spotless today.  AR2882 is gone but managed to accumulate a total active region area during the time it was visible of 3370 millionths, which is the third largest so far in Cycle 25, compared to AR2786 which reached 7300 millionths.  Some nice proms are also visible at the western limb.  Today only full disk images in the three wavelengths.

Clear skies with average seeing.  AR2882, while still covering 250 millionths, is quiet and getting ready to follow AR2885 by rotating around the Western limb.  Some nice proms on the SW and the NE limbs.  Full disk images and close ups today.

For today’s session the weather was great, with great seeing.  We have one Active Region left, AR2882, while according to SWPC, AR2883 decayed to a plage this morning.  However, a very nice prominence is visible at the SW limb, which seems to be an extension of the filaments which strech along the edge almost from South. The umbra of the AR2882 seems asymmetric with the penumbra being encroached from the SE and SW.   Today full disk images with close ups of the region and the prom/filaments.

Clear skies with good seeing conditions.  We have two new named areas on the Solar disk: AR2880 and AR2881. One of the filaments around AR2871 did create a CME yesterday morning which has been modeled at a speed of over 800 km/sec.,  which will arrive at the end of today, or early tomorrow.  So look out for Northern Lights. The Daily Total Active Region Areas for today is at 170 millionths.  Full disk images in the three wavelengths as well as close ups of the mentioned regions.

Good seeing this morning.  The Sun is busy with named regions, but they are hard to see in white light.  The two old regions AR2871 and AR2872 have decayed some more, but AR2871 looks great in the Ha close up with the swirling filaments.  AR2877 and 78 are pretty much stable, and today SWPC named also AR2879 at 13N24W.  The total active region area for today is 170 millionths.

Clear skies with good seeing.  Two named Active Regions today, AR2871 and AR2872.  AR 2871 is still a very interesting area and shows mixed polarities in SDO’s magnetogram, while AR2872 is decaying very much.  Today two small new named areas were named, both in the SE quadrant.  AR2877 and 78. And although I did not make out any spots in AR2877,  I did see spots in AR2878.  The Total daily Active Region Areas for today is 200 millionths.  Today full disk images and closeups in all wavelengths.

Clear skies again today!  AR2874 became one of those short-lived spots of 1 day, much like AR2870, AR2867 and AR2865 in recent days were also 1 day Spots.  AR2871 produced an M1.8 flare with a subsequent CME.  Total daily Active Region Areas today is at 350 millionths. Full disk images today and close ups of the mentioned regions.
