Bullet Photometric Monitoring - Variables
  - SY Cnc, RZ LMi, R CrB, U Gem, DY per, GK Per, RR Tau, ER UMa
   
Bullet Astrometric Monitoring - Nearby Stars
  - None
- Evening session (2.2 hrs duration).   Clear sky.
An aurora display began later on at 1:30am.
- Session operated under semi-automated control, with remote monitoring from indoors computer.  
- Ambient Temperature:  minimum of +4.5°C
- CCD operation -25°C (at 76% average cooling). 
- Main objectives of the session was to monitor selected variable stars & nearby stars and to take gallery images of a selected deep sky objects  (including several members of the M51 Galaxy Group)
    
- Notes:
RZ LMi images (90s, C filter, -25deg C) wouldn't link until after a Hot Pixel repair operation is performed.
