Objects Session Notes
17P/Holmes - Comet 93P/Lovas - Comet NGC 1058 - Spiral Galaxy UGC 12846 - Spiral Galaxy with Supernova 2007od IC 1613 - irregular galaxy, local group Astrometric & Photometric Monitoring
- SS Cyg (dwarf nova)
- BL Lac (Blazar)
- U And, W And (mira variable)
- RX And, TT Ari (variables)
- CY Lyr, TZ Lyr, Z And (variables)
- Barnard's Star, 61 Cyg, Teegarden's Star (Nearby Stars)
- Evening session (7.4hr), operated under automated control for majority of session. Cold for 5-6 hrs, but then temperatures rose by 5 deg and seeing deteriorated as a warm front came through. Eventually thin cloud developed. CCD operation of -25 degC (at 67% average cooling). Backed off to -20 degC from last part of session. - main objective of the session was to acquire an image mosaic of comet 17P/Holmes (now grown to larger than the apparent diameter of the moon) -secondary objectives were to acquire images of certain selected stars of ongoing photometric and astrometric analysis -opportunity was also taken to acquire gallery images of Caldwell 51 (IC 1613), and certain other comets and deep sky objects.
