Comments: 

1) the green circle on the RAMSICAM doesn't point to the direction of the telescope

2) a number of group members reported that when trying to logon to the observer console at the beginning, we get error message saying "invalid prop id". But then works randomly after trying 4 or 5 times.

3) the dimmer camera was not working

4) 12 min before the handover everyone got kicked of the VPN and the VNC so that was quite hectic. For the past 4 nights, several people have been kicked off during this hand over. There are issues with the VPN connections.
