Bullet Astrometric & Photometric Monitoring
- HD 5501/5513 (eclipsing variables)
- SS Cyg (dwarf novae)
- BL Lac (BL Lac blazer)
- U And, W And (mira variables)
- Z And, T Tau (variable)
- Teegarden's Star, 61 Cyg (Nearby Stars)
- 6.6 hr session, largely operated under automated control
- CCD operation of -25 degC (at 66% average cooling). .
- main objective was to acquire additional frames to extend a large scale image mosaic of M31 collected during previous session, along with acquisition of images as part of variable star monitoring.
