Bullet C/2006 M4 (Swan) - Comet
Bullet M31 - Spiral Galaxy (Mosaic)
Bullet M31 - Extragalactic Nova: M31 2006 14
Bullet Astrometric & Photometric Monitoring
- HD 5501/5513 (eclipsing variables)
- SS Cyg (dwarf novae)
- BL Lac (BL Lac blazer)
- 6.5 hr session, largely operated under automated control
- CCD operation of -25 degC (at 55% average cooling). .
- main objective was to acquire a large scale image mosaic of M31, together with follow-up images on C/2006 M4,  SS Cyg, BL Lac and M31 Nova (2006 14)

M31 - Extragalactic Nova : M31 2006 14

M31 part (Andromeda)
An extragalactic nova (M31 2006 14) was discovered in M31 on 2006/11/25.468
by Koichi Itagak, with an apparent magnitude of +17.5 
(Extragalactic Novae page at Rochester Supernova site | Discovery Image | Reference: 2006-11a)

Image below (2006-12-10.00) shows that object (shown by white marker) is still visible, 
despite the bright moonlit sky background
Estimated magnitude +16.1 . Limiting Mag +16.5
