Transits are now underway, but aprox 15 minutes after commencing, I can still see the white little discs of Europa and Io in front of Jupiter. Io is the more easily seen, its brighter, started later and also is in front of one of bands.

Both Moon's shadows appear on Jupiter tonight. Ios from about 9.30pm and Europa's from about 10.45. Both are on Jupiter from then to when Io's shadow leaves Jupiter from about 11.40.

Also worth seeing is when the Moons finish their transits within about 15 mins of each other from about 10.30.

Hope the weather holds. Last week I tried to see this, but the seeing was so bad that I could only pick out Io's shadow.
