Session Aims & Highlights (2024-02-22)

Main aims

  1. Targets.  Acquire images of a selection of variable stars, nearby stars, comets & deep sky targets as allowed by sky conditions.
  2. 12P/Pons-Brooks. Acquire images of Comet 12P/Pons-Brooks which has been undergoing regular outbursts.
  3. Nova Per 2020. Aquire images of Nova Per 2020 to confirm or otherwise dismiss the apparent brightening of the star from mag +17.80 (T+1137.1d, S1179) to mag +16.36 (T+1182.2d, S1187) , apparently reversing the overall decline in star brightness since it erupted in 2020.
  4. Nova Cas 2021. Aquire 3 x 300s spectra exposures images of Nova Cas 2021. With declining brightness in the existing 90s exposures aquired in session S1188 are too short to obtain sufficient signal/noise ratio, and 300s exposures are proposed. This will also entail getting a set of 300s dark frames at same CCD Temperature.
  5. AstroMain. Continue to test fixes to CCDSoft Camera/SBIG Camera operations to prevent stalled execution during starting, fix issues due to occasional repeated failures during Cam1 focusing and occassional unexpected CCD Temperature regulation.
