Session Notes

C/2009 P1 (Garradd) - Comet M101 - Spiral Galaxy with Supernova 2011fe     Photometric Monitoring - Variables - None   - R CrB attempt (failed due to cloud)     Astrometric Monitoring - Nearby Stars - None - Barnards Star attempt (failed due to wind)

- Short evening session (0.6 hrs), cut short due to cloud & wind - Session operated under semi-automated control, with remote monitoring from indoors computer.  - Ambient Temperature: 13.5°C (minimum)  - CCD operation -20°C (at 86% 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 -

M101 - Spiral Galaxy with Supernova 2011fe

M101 with SN 2011fe  (Ursa Major) SN 2011fe (= PTF11kly) (Type Ia) was discovered  2011/08/24.00 by Palomar Transient Factory Discovery Magnitude 17.2 ( Rochester Supernova site | Discovery Image | TNS 2011fe )		SN 2011fe is reported as being the  nearest Type Ia supernova  seen in decades
M101 with SN 2011fe (brightening) Poor quality image  (Poor sky transparency + frost on edges of CCD)
