Bullet Variable Stars
Bullet Photometric Monitoring - Variables
- RX And, Z And, TT Ari, R CrB, CI Cyg, S Cyg, SS Cyg, U Her, BL Lac, SZ Lyn, DY Per, GK Per

- SS Cyg (Time Series)

Bullet Astrometric Monitoring - Nearby Stars
- Ross 248 (HH And), 61 Cyg, Groombridge 34, EV Lac, Teegardens Star
- Evening session (6.2 hrs duration). 
Moderate conditions, wind affecting some images 
- Session operated under semi-automated control, with remote monitoring from indoors computer.  
(Power-Line networking - no detectable drops outs in over 6 hours).
- Ambient Temperature: -1.0 deg C (minimum) 
No problems with dew at all during session - surprise !
- CCD operation -30 degC (at 70% 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 deep sky objects
