Objects Session Notes
NGC 1015 - Spiral Galaxy & Supernovae 2009ig 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)
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.
