2022-01-09 18:38UT We are starting the 2022 solar observing campaign. The day had clear skies, but only average seeing conditions. We start with a full disk composite of exposures for surface detail and prominences.
2022-01-09 18:55UT to 19:39UT We follow with a few prominences details picked up with the 3x TV Barlow. The seeing really was not good enough to support this magnification.
