Session Notes

M101 - Spiral Galaxy with Supernova 2011fe Photometric Monitoring - Variables - RX And, Z And, KR Aur, CI Cyg, SS Cyg, BL Lac, DY Per, GK Per, RR Tau - FO And, W And, CN Ori, FO Ori, FU Ori, FG Sge Attempts (failed due to cloud or wind) Astrometric Monitoring - Nearby Stars - None

- Session in two parts - Late Night session (0.75 hrs)   00:40 - 01:22 hrs  - Evening session (1.3 hrs)   22:30 - 23:55 hrs - Session parts operated under semi-automated control, with remote monitoring from indoors computer.    - Ambient Temperature:  - Night Session  5.5°C (minimum)  - Evening Session 1.5°C (minimum) - CCD operation - Night Session  -25°C (at 61% average cooling).   - Evening Session -25°C (at 67% average cooling).   - main objective of the session was to acquire images of selected project stars for ongoing photometric analysis and to test a new software routines for providing regularly (every 2 sec ) monitoring of the observatory hardware and software connections. -
