- All Night session (1.4 hours)
- Main aims of the session were to acquire a selection of variable star, nearby star and comet targets and deep sky targets as cloud allowed
- Session start delayed by show-stopping issue with AstroMain program vn 3.38.11.  After dropping back to 3.38.10 session commenced but was quickly cut short by developing cloud.
