We had a brief clearing here,and I decided to venture out and observe Jupiter.
  It was immediately obvious that there was a dark speck in the STB and at first I thought it was a satellite shadow. 
 A quick check of WINJUPOS revealed it to be Callisto in tgransit!
  I have been waiting for a Callisto transit for sometime,and it was nice to catch it albeit by chance! 
 Against the disk of Jupiter it is rather dark and I would assign it a BAA scale of 8.5.
  I also examined with a number of filters:


W#25A: Harder to see in this filter and it seemed a little brighter,perhaps around 8.0
W#80A: Much easier to see in this filter.  The intensity is probably the same as IL
W#47: Jupiter rather faint in this filter although the two main EBs can be seen.  Callisto was not seen however.
W#58: In the green filter Calisto seemed to be lighter.  I would assign it a value of around 7.5.
  In this filter it appeared to be a dark greyish colour.

By 1946 the wind was rather strong and thick clouds arrived once more.  A short but rewarding observation

NTB北縁の白斑ですが、メタン画像に目立つ模様は見えません。
大赤斑後方のSEB付近が、メタンで明るく見えます。

まだ寒気がいすわり高度が高い割になかなか気流が安定しません。

At long last,we had clear skies again in Belgium with decent seeing conditions as well.
It was a nice opportunity because Callisto passed Jupiter and the GRS was also visible at the same time.

Here's an RGB result. I made Callisto a little bit brighter because it is a very dark moon

Seeing and transparency were poor.

Here is an image from Feb 22nd. Io alongside the planet with Callisto in transit (the moon itself not its shadow.) 
The NNTZ LRS looks rather like a jovian red eye in this shot. Average seeing and transparency.
