20171211 Sun

Winter means poor transparency due to the wind from mainland, and it usually means poor seeing with sharp temperature changes.


0550 (UT), no fine detail could be seen.


0552 (UT), push up exposure to show the prominence.

20171208 Sun

Seeing no good again, temperature is dropping since yesterday night so it accounts for the poor seeing.  The solar disc is kind of featureless too.

0617 (UT), extremely poor seeing, dare not to further process after this stacked wavelett processed version.  Just a record.

20171117 Sun

Seeing bad, transparency 4/10.


0617 (UT), there might be a small active region forming at the right near the center, but the most interesting feature is the filament at the 3 O'clock position and it extends beyond the solar disc as a prominence.  Not very big, however.

Cloud moving around, the AVI was not stackable.

Only a very subtle filament available visually.

Just a record.
