Objects Session Notes
AT 2024vlc - Type CV? Transient AT 2024wqf - Type AGN Transient (4C 27.50) AT 2024xpy - Type BL Transient NGC 908 - Spiral Galaxy (Hidden Treasures 9, H I-153) PGC 3792 - Local Group Galaxy (Pisces Dwarf), 3.0 mly Variable Stars (photometric monitoring) - BL Lac - T CrB attempt failed (due to cloud/poor centering) Nearby Stars (astrometric monitoring) - None
- Night Session (6.7 hrs), badly compromised by cloud and bright aurora-lit sky. Telescope connectivity lost at 03:14. - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: 5°C (min) - CCD Temperature: -20°C - Notes from 2024-10-10 >> - Aurora Images/Video from night, 2024-10-10/11 >>
