- In this night I was able to observe Jupiter extensively. The seeing was getting worse during the night, 
but I could collect enough sketches for a nearly complete map of Jupiter - only the area between 74 - 124 is absent. - For the first time I saw the small D-SPOT on the southern edge of the SEB, shortly before the GRF.
When I started with my observation, it was more or less at the ZM. - Since my last observation on 2016-03-26 the wake changed slightly - the two "cuts" at about 300 and 330 were new to me.
In general, the wake currently has a truly impressive length. - The area around the WOS BA I could only see as elongated darkening - the seeing was quite bad at this time. - At 340 the NEB was almost as wide as the SEB. Right and left of WSZ I could see two dark blue D-PROJ.
Observed through a red filter, they appeared almost black. [Michael Kassl : Carinthia,Austria]
