I have to agree that there being a Moon during the night is a pain and I doubt that the group planning the event even considered the Moon phase. The main reason for the event timing is because of Science week.
As I'm running the observing session for the public so I won't be getting any observing or imaging in anyway.
Moon rising 10min before midnight is good for people who haven't seen the Moon through a scope before and being a wanning 1/4 phase it will have a nice terminator.
Even with a Moon putting a spanner in works the whole event of the Day and Night is going to still be great one.
