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.

Well the cold came.  Temperatures in the 30’s this morning, but with it came clear skies.  The current spotless streak will end now with 29 days, short of the 33 and 36 days from earlier this year, but well below three streaks during the previous minimum of 44,  51 and 52 days.  The area popped up at a longitude of 117.7 degrees and South 27.4 degrees and shows a polarization consistent with Cycle 25.  A few prominences were also visible at the Western limb.  Today full disk images as well as close ups in Ha and 540nm of the new area.
