Sunny skies again and for a change it was relative stable enough for a WLC close up, but not good enough for a crisp image.  Today AR2205 is dominant at 350 millionths and is shown at the peak of an M 2.3  flare in the close up.

Clear Skies again good enough for a full disk image and close ups of 2205 with a nice M2.3 flare and a nice prom, but not stable at all for WLC.

Sunny day again with a full disk image and two close ups in the morning,  and a special ISS-Sun transit image for the afternoon.  With the ISS image I did want to test the data transfer performance of the ASI120MM with my laptop.  Whereas I always lost a frame or two with the DMK21 even at 15 frames per second, the ASI ran at 54 frames per second and did not have any lost frames. For this image I did eliminate every other image in the AVI in order to reduce the processing time.  Very happy with this!

The Sun is a lot calmer than it was last week.  Only a few C class flares in 2205 and a nice prom at the West side.  The weather was too unstable for an WLC image.

The sky was very calm this morning with great transparency until the clouds started rolling in! I managed to capture another great shot of the largest spot in AR2192.  AR2192 has shrunk to 2380 today and the next two days will be clouds, so transparency will not be good.  After that the region will have “turned around the corner.”

Today AR2192 caused another X2.0 flare.  I noticed it when I checked the SM40 after finishing the visible light imaging, so I caught the end of the flare.  Today the sky was much more stable with relative good seeing, so I captured an image “Inside of the largest spot of AR2192″  The large filament in the northern hemisphere is beautiful.  AR2192 is growing again, today its at 2750 millionth.

Yesterday the seeing was great compared to today, so today’s visible light image is not very sharp, but the contours of the spot still look great. This is a prime focus image with the C11 and a WL and continuum filter.

AR2192 produced an X1.0 and an X3.2 flare in the last 24 hours.  Its size has also increased a little to 2570 again.  It seems it does not want to give up yet.  Pretty soon it will be disappearing behind the Western limb and we will have to wait until it comes around again

This is how the region looks through my C11 with a Baader Photo filter and a continuum filter.  This image has been taken with a 0.6x focal reducer in front of the camera in direct focus.

I guess the Sun was waiting for the Solar eclipse to max out AR2192 as it reached 2740 on the 24th.  Today its size went down to 2510, but it produced a X3.2 flare last evening.  The Sun was too low for imaging from my site.  Here a full disk and close up if AR2192 on the 25th.
