2月20 25日による、Rで捉えたBAと大赤斑の動きです。

Hello again,
I had recently a number of imaging sessions with very bad seeing, and also
very few spare time to prepare all the raws/sessions that have been
obtained this month.
Here is a sample of the images I got, using the two most recent sessions
with acceptable stability (Feb 20 and 25).
The IR and CH4 images were used to prepare cyllindrical projections in
JUPOs using the protocol I referred in one of my previous messages.
On both dates the CH4 counterpart of BA continues to co-localize
approximately with the center of the larger IR image of BA. GRS and BA
continue to be two distinct structures without any apparent distortion in
the CH4 band.
Also on both dates, the CH4 data shows some small bright clouds in SEB
following the GRS.
Good observations
Antonio
