Objects Session Notes
Bullet NGC 1015 - Spiral Galaxy & Supernovae 2009ig
Bullet Photometric Monitoring - Variables
- RX And, U And, W And, Z And, TT Ari, R CrB, 
- KR Aur, HR Aur, CI Cyg, S Cyg, SS Cyg, AM Her
- RU Peg, DY Per, GK Per, KT Per, TZ Per, 
- FG Sge, V Sge, RR Tau, ER UMa

- R CrB, U Her, BL Lac, U Sge attempts (failed due tio wind shake)

Bullet Astrometric Monitoring - Nearby Stars
- None
 
- Late evening session (3.7 hr). Sufficient wind to necessitate removal of dew shield to obtain suitable image quality. Early images discarded due to wind shake/star blurring.
- Operated under semi-automated control with remote monitoring
- Ambient Temperature  13 deg C falling to 11 deg C (minimum)
- CCD operation -20 degC (at 79% average cooling).  
- main objective of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis.
