[paulastro]

 

Just posted this on Observing - Planetary, but I suppose those engaged in the dark arts may see it as an opportunity too!

 

I’m sure you already know, but don’t forget the multi-shadow transit event on Jupiter tonight.  Up in darkest Yorkshire I don’t expect to see any of it, but you never know, and I’ll be ready at a moments notice!

 

 

Here are the satellite phenomena for Sat night/Sunday morning.  Taken from S&T’s interactive thingy. Remember to add an hour to convert the times to BST !

As you can see, the critical time is 01.18 to 01.44 Sunday morning.

No luck here. Seeing was choppy to say the least to begin with. Clouds came in before the main event

Sorry you had no luck Michael.  It was overcast, drizzling and windy up here!
