The comet 2017K2 PanSTARRS in that day has positioned in the Milky Way around northwest edge of Aquila with a 10th magnitude coma after midnight. Now the comet has almost no apparent movement, moved only a degree westward from my previous observation a month ago. The comet will be observable at northern hemisphere until autumn of 2022, and brighten up around 5th or 6th magnitude visible at southen hemisphere in the end of the year.
  View angle: 0.70×0.70°
