Session Aims & Highlights (2022-11-27)

Main aims

  1. 29P/Schwassmann-Wachmann. Acquire further images of 29P/Schwassmann-Wachmann, as followup to images taken in last two sessions (S1061 & S1062) . Look out for expanding coma following recent 4 mag outburst
  2. Targets.  Acquire images of a selection of variable stars, nearby stars, comets & deep sky targets as allowed by sky conditions.
  3. AstroMain.  Check new AstroMain version (3.58.5) for any issues introduced by several recent changes, bug fixes and additions.

Note on FITS Date/Time Format
You can safely omit the Z suffix because of the presumption of UTC stated on page 12 of the FITS definition ( https://fits.gsfc.nasa.gov/standard40/fits_standard40aa-le.pdf ): "The value of the DATE keyword shall always be expressed in UTC when in this format, for all data sets created on Earth.". In addition, section 9.1.1 (page 37) of the FITS definition states: "As specified by Bunclark & Rots (1997), time zones are explicitly not supported in FITS and, consequently, appending the letter ’Z’ to a FITS ISO-8601 string is not allowed.".
