Objects Session Notes
No Images Photometric Monitoring - Variables - SS Cyg, BL Lac, DY Per, GK Per
(SS Cyg, BL Lac attempts failed due to cloud/poor transparency)Astrometric Monitoring - Nearby Stars - None
- Session in two parts
S556a 2013-11-24
- TPoint Mapping / Polar Alignment Check
S556b 2013-11-27
- Imaging/Slewing Checks & Tracking Rate Checks-
- 2013-11-27 Late Evening session (0.9 hrs duration). Poor sky transparency - Session operated under semi-automated control, with remote monitoring from indoors computer. - Ambient Temperature: 3.0 degC minimum - CCD operation -25 degC (at 68% average cooling). - main objectives of the combined session was to continue preparations towards an effective return to imaging, concentrating on the following
- TPoint Mapping
- Polar Alignment Check & adjustment (* see note)
- BVR imaging of selected variables (including a test of slewing accuracy with TPoint model running)
- tracking rate and adjustment
* Polar Alignment adjustment was not able to be performed due to deteriorating sky conditions- Notes 2013-11-27
