04:28 the sky is completely covered by clouds

04:48 conditions are better, we send ngc4579_mods.obs

  • seeing 1.0
  • clouds during the first integration
  • 06:17 lost guide star, stop exposure texp=1300, spectra look good

06:21 The TO closes the dome

07:04 The TO opens the dome, the sky is 80% clear

07:15 we slew to Israel A5
