After a poor start to this month, seeing was excellent on this ocassion, permitting very fine views. I spent time observing Ganymede at 586x, and definatly saw the marking depticted in the attached image. Unfortunatly though, Jupiter's least active side was visible, apart from at the very end of the session, when i caught the Planet disappearing out of view from my site. The last images show Oval BA very clearly, and it looks rather chaotic. Note the faint streak running across it. Also of note are the STrZ dark spot, showing a distinct deflection of the SEBs around it. Also the faded sector of SSTB is passing BA to the South.
