Clear skies with great seeing.  Another spotless day for spotless day 483 since Solar max.  A faint prominence at the NW limb and a few small filaments.  Full disk images today and a close up of the filaments with the ASI174 and ASI120.

The clouds made the Sun play hide and seek, but I finally was able to catch some full disk images.  Another spotless day, and we see a small area popping up not too far from the Eastern limb near the equator shown as a small plage in the CaK image.  This area is C24 polarized. Happy 4th of July!!!

Clear skies with good seeing.  Another spotless day but the reverse polarized area I mentioned yesterday, has continued to evolve and is now very well visible in Ha also.  However, no spot or pore was seen at the time of my session.  I used the time to do some comparison images of closeups with the new ASI120MM-S.  Will discuss this at another time.  Today full disk images and close ups of the mentioned areas including the filaments in the northern hemisphere.

High thin clouds this morning.  Another spotless day.  The Filaments at the NE and NW limbs are still nicely visible.  However, a small reverse polarized active area has developed at 20 degrees South near the Meridian and is visible both in the Ha and CaK full disk images.  It looks like it might break up already, so we’ll see how this progresses.

The first (spotless) day of a new rotation with below average transparency.  Focused today again on the two filaments in the Northern hemisphere.

Good seeing, but below average transparency today on another spotless day.  However, I was able to test my new ASI120MM.  In direct focus everything is fine, and with low magnification and the tilter, things work fine also.  I now have been able to get rid of most of the concentric rings, whether they are Newton rings, or caused by USB3 interference.  So today I am attaching full disk images captured with the ASI174 and close ups of three images of the small northern filaments captured with the ASI120.  One in direct focus, one with 1.6 magnification and one with 3x magnification.  So far I feel good about it.

A brief time with good seeing, but than the clouds took over.  AR2742 was very short lived, but AR2743 still shows near the Western limb. Did image the active region and the filaments in the Northern hemisphere, but did not have time for the NE prom.  The stats for today are: total active region areas 10 millionths and 2 spots.

Well, the spotless streak is coming to an end.  Two small areas started showing up yesterday in the western hemisphere very close to the equator.  By 1200 UT today, one of them was named AR2742.  However, flaring is very minimal.  Also the northern filament is still there and even becoming more prominent.  Unfortunately the clouds made it a very frustrating 2 1/2 hour session, but I got a close up of both the filament and the regions.  However had to do it using the ASI174MM capturing a lot of data.

Another spotless day.  Scattered thin clouds everywhere today so had to image through some moving clouds which required me to resort to Registax 5 to process some of the images.  The small filament is still there and I made again some close ups of it with different magnifications and the ASI120MM.

Clear for a short while until the clouds took over.  What’s new?  Another spotless day.  Today we exceeded the previous longest spotless streak of 33 days (SWPC).  My plans to image some more with the ASI120MM came to an abrupt end as the clouds took over.  So today a compromised Ha full disk image, and a non-compensated image of the Northern Filament using the 2x barlow.
