Objects Session Notes
12P/Pons-Brooks - Comet 207P/NEAT - Comet C/2022 E2 (ATLAS) - Comet AT 2024djo - Type MP Transient AT 2024dof - CV Type Transient AT 2024dsj - CV Type Transient NGC 1122 - Spiral Galaxy with Type Ia Supernova 2024dru NGC 3206 - Spiral Galaxy with Type IIn Supernova 2024bch - UGC 831 with SN 2023wdd attempt failed (cloud / poor sky transparency) - Segue 1 attempt failed (due to dome azimuth issue & occluded sky view) Variable Stars (photometric monitoring) - None Nearby Stars (astrometric monitoring) - None
- Evening Session (4.1 hours) ended early due to issue with Pulsar Dome loosing its azimuthal position after a power outage test which saw a complete of all the dome's settings. At around the same time, the sky clouded over , with overcast conditions lasting until dawn. - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: 5.5°C (min) - CCD Temperature: -15°/20°C - Notes from 2024-03-13 >> -
