 - None
    
   
- Short evening session,  Duration 1.1hr

Session operated in  fully automated mode, and monitored over remote connection.

After a promising start cloud rapidly rolled in and brought the session to an end.

- Main aim of the session was general observing with mix of variable stars, nearby stars, comets and deep sky targets.
