11.3.20

11.03.2020 Solar southern hemisphere AR.

*


Wednesday 11th: Gales from the west with lots of thick cloud racing across.

Only brief moments of sunshine. Protected from the wind by the easterly dome rotation.

New version of SharpCap 3.2 installed. It couldn't find the ASI174 camera afterwards!!

Found the AR on mid line in southern hemisphere. Capturing 800x600. 1k, 2k & 3k frames in 3, 6 & 9 secs.

0.8ms at 320fps with zero gain.

Images processed in AS!2, iMPPG and PF7. Using 100 of 3000 frames. Images captured at 11.31, 11.44, 11.53, 12.00 and 12.08, etc.


Despite increasingly obvious, thermal effects on the monitor image the seeing seems to be improving with time. Cloud thinning too.

Processing takes only a couple of minutes from capture.

Blogger won't let me have two vertical columns of images on either side of the text.



But now it will! The individual images may be out of order by now but each has its time of capture in the name if you hover over it with the cursor.


The first image after lunch was captured at 14.53. The "seeing" is going off. The filament has already changed.Then gone.

Clear skies now so I shall continue capturing videos for as long as possible. Hopefully the wind will reduce.



Still plodding away as the sun sinks in the east behind the trees.
15:18 and 15.25 right through to 15.56.

I shall have to add the time of capture to each image in PF7.





The final image is of a prom at about 2.30 o'clock on the the western limb. I should have checked Gong Ha for proms much earlier.
