- RX And, U And, W And, Z And, R CrB, CI Cyg, S Cyg, SS Cyg, U Her, BL Lac, DY Per, GK Per, FG Sge, U Sge, V Sge
Bullet Astrometric Monitoring - Nearby Stars
- None
- Evening session (3.1 hrs duration). 
Moderate conditions
- Session operated under semi-automated control, with remote monitoring from indoors computer.  
Second use of Power-Line networking (regular dropout of connection at 4 min 5sec intervals, reason unknown but resolved by setting Auto Reconnect On in the VNC viewer) 
- Ambient Temperature: 3.5 deg C (minimum) 
Dew requiring corrector plate to be cleared with hair dyer on 2-3 occasions.
- CCD operation -25 degC (at 69% average cooling).  
- main objectives of the session were to acquire images of selected project stars for ongoing photometric and astrometric analysis, and to image a number of planetary nebula
