Objects Session Notes
Bullet Comet C/2007 B2 (Skiff)
Bullet PGC 29488 / Leo I - local group galaxy
Bullet M67 - open cluster
Bullet M87 - Elliptical Galaxy / Jet
Bullet NGC 4567/4568 - spiral galaxies (Siamese Pair)
Bullet NGC 5394/5395, ARP 84  ("Heron")
Bullet Astrometric & Photometric Monitoring
- U Gem (dwarf nova)
- KR Aur, AQ CMi, CV CMi, SY Cnc, U Mon (variables)

- Wolf 359 attempt (but images couldn't link)





- Late Evening session (3.3hr).  
Temperature +0.8 degC, later rising to +2.5 degC
- CCD operation of -25 degC 
(at 69% average cooling). 
- main objective was to acquire images of certain selected stars for ongoing photometric analysis, in particular U Gem & RX And. 
- opportunity was also taken to acquire a number of gallery images of specific ARP galaxies .
