Clear skies again with average seeing.  Another day with a spotless Sun. We still observe the plage in the Southern hemisphere and a filament in the NW hemisphere in Ha.

Intermittent clouds today, but I was able to get some images.  A spotless day again for spotless day 608 since solar maximum.  Solar Activity remains Very Low. We continue to see the remnant of AR2752 as a reverse polarized area.  Today’s full disk images and a close up of the mentioned area in Ha.

Well, yesterday I was notified that the Minor Planet 2000 EM20 discovered by the Catalina Survey on March 3rd 2000, has been designated as (71615) Ramakers by the International Astronomical Union. So now you can visit me not only in Oxford but also in space! Thanks to  Richard Hill for being the driving force behind this.

Clear skies with poor seeing today.  A new active area has come around the Eastern limb in the Southern hemisphere which is visible in all three full disk images.  The region was named in SWPC’s midday report as AR2752. The area also seems to be reverse polarized. In addition to his area we see a very small reverse polarized area in the NW quadrant.  A few prominences in the  SE and NW sum up todays activity.  Full disk images today as well as close ups of the new region in CaK.

The Mercury Transit 2019.

Well, it did not start good, and did not end good, but in between I was able to capture some images which were compromised by lots of clouds.  The first image that resulted in making out that Mercury was there, was at 1338 UT.  However the blotched image shows what we had to deal with.  During the second half of the transit it was not much better and resulted in only one image towards the end of the transit.  The goal was to capture images in half an hour intervals. Here six images recapping the event for 2019, which is totally different than the 2016 event, during which I was able to capture composites of the ingress and egress.

Another very cold but clear morning with great seeing.  No spots on the Sun, but another reverse polarized area at N23 degrees and a longitude of 70 degrees.  In addition, we observed some prominences. Today marks the 600th spotless day since Solar Maximum.  Today full disk images and close ups in Ha and CaK of the reverse polarized area and two of the proms.

Another cold morning with clear skies and good seeing today, but no spots to observe.  However  a small reverse polarized area did become active for a while near the meridian at North 13.8 degrees.  I will add this to my overview later today. Today full disk images and a few closeups in Ha and 540nm.

Clear skies today, but a spotless Sun.  A few small proms were visible in the NE and the West and NW. Today full disk images as well as a close up of the filament in the North in Ha.

Cold again but clear skies! AR2750 has decayed and now only can be seen as a plage.  However the area in the western hemisphere was named  AR2751, but has decayed a lot today.  Today full disk images and close ups of the two regions in Ha and CaK.

Another cold day with clear skies.  The new spot from yesterday was named AR2750, but it had decayed quite a bit since yesterday, but it is still visible in the images.  The other area which has been observed as a plage since the 28th at a latitude of around 3 degrees North, now seems to have developed a spot and shows some flaring, but is polarized as a cycle 24 area.  So we will be looking if that will be named today.  Full disk images today and close ups of the mentioned areas.
