Session Notes

NGC 2770 - Spiral Galaxy & Supernovae 2007uy and 2008D NGC 3978 - Spiral Galaxy UGC 3611 - Spiral Galaxy & Supernova 2008C Astrometric & Photometric Monitoring - SS Cyg, U Gem (dwarf nova) - BL Lac (Blazar) - TT Ari, RX And, Z And (variables)

- Late evening session (2.7hr + 1 hr for telescope tuning). - CCD operation of -25 degC (at 64% average cooling).  - main objectives were a) to acquire images of certain selected stars of ongoing photometric and astrometric analysis, in particular SS Cyg and b) record further follow-up images of 2 supernovae in NGC 2770.  - a polar misalignment issue introduced two sessions ago was examined at the end of the imaging run using the Drift Method and a 6 arc min clockwise adjustment was made to the telescope mount. Cloud prevented a check on the polar axis inclination. - PEC (RA) training was performed using 3 x 8 minute autoguided runs.
