Jupiter & Io Shadow Transit 13 September 2011

[DarkerSky]

Rolled out my 16" on Tuesday night to spend some time on Jupiter. Seeing was a bit iffy .. A IV most of the time That said, there were a few good moments that allowed me to capture this:

16" x228 magnification

22.40 to 23.25UT

CM1: 281 degrees approx

CM2: 51 degrees approx

The main dark feature centred over the SEB is the shadow of Io, which was in transit across the disc. Couldn't make out Io itself, which I put down to the poor seeing.

The other feature that really intrigued me was the brighter spot in the EZ, right on the northern edge of the SEB near centre.

Brilliant sketch,i was viewing the night after and seen the same dark spot on the NEB,thought it was Io's shadow then realised i got the date wrong for the transit.

Another nice drawing Seb, it's always great to catch a transit/shadow transit.
