  • Dome entered at 10am, present CM SH AS JC
  • Telescope cover removed, solar filters put on
  • camera set up removed from previous observation
  • colour filters and camera DMK 21AF04.AS attached and fire wire connected to telescope
  • telescope turned on and GPS fix taken
  • dome doors opened and slewed so shadow aligned on wall behind telescope
  • telescope moved so its shadow was minimal in size and the shape of the solar filter was visible
  • astronomical tracking turned on and manual focussing completed by turing focus knob
  • using live feed of IC Capture, image moved to approximate equator
  • 11:20 observation began
  • red filter positioned in front of camera
  • speed 3 slewed to right for 20 seconds
  • sequence timer set for 405 seconds 1 sec interval
  • red_drift taken (exposure 1/3003 gain 1023)
  • scan aborted due to tree blocking image, file changed to red_drift_badrun
  • 11:50 observation restarted
  • red_drift drift scan taken file uploaded to slack (exposure 1/1000, gain 1023)
  • red filter changed to green moved to centre of sun and exposure altered (exposure 1/700, gain 1023)
  • green_drift file uploaded to slack
  • green filter changed to blue (exposure 1/367, gain 1023)
  • blue_drift file uploaded to slack
  • blue filter changed to clear (exposure 1/10000, gain 1023)
  • clear_drift uploaded to slack
  • blue filter used again (exposure 1/367, gain 1023)
  • blue_redrift aborted due to cloud cover of at least 10 frames
  • blue_redrift1 started with same exposure and gain values
  • blue_redrift1 uploaded tp slack
  • dome doors repositioned above motor and closed
  • telescope slewed to 0h0d
