Objects Session Notes
M101 - spiral galaxy with supernova 2011fe C/2009 P1 (Garradd) - Comet NGC 6742 - Planetary Nebula (Abell 50) PN G75.5+1.7- Planetary Nebula ("Soap Bubble Nebula") Abell 4 - Planetary Nebula Variable Stars Photometric Monitoring - Variables - RX And, U And, TT Ari, CI Cyg, S Cyg, SS Cyg, BL Lac, CY Lyr, DY Per, GK Per
- W And, Z And attempts (failed due to cloud)Astrometric Monitoring - Nearby Stars 61 Cyg, Ross 248 (HH And), Groombridge 34
- Evening session (4.6 hrs), cut short due to wind - Session operated under semi-automated control, with remote monitoring from indoors computer. Observatory laptop froze on one occasion requiring a restart - reason unknown. - Ambient Temperature: Falling to 4.5 deg C (minimum) before climbing to 6.5 degC - CCD operation -20 degC (at 60% average cooling). - main objective of the session to obtain follow-up images of bright supernovae in nearby galaxy M101 secondary objective was to image project stars for ongoing photometric analysis and image certain challenge & gallery objects
