It says April 16 on the image, cause it's captioned in UTC, but these were taken this morning in the subzero canberra climate...
The best seeing around here happens just a couple of hours before dawn but jupiter is low in the west by that time, and when it's high in the sky around midnight the seeing is normally very bad. It looks like jupiter season is almost past for me from Canberra - I'm holding out for a couple of weeks of good conditions in Rockhampton.
Hubble was scheduled to image Jupiter at around 18:17UTC, it was really cool to think that I was imaging at the same time... I hope they had better seeing :-)
