Observation Notes (using the view orientation for discussion)

• the comet had a noticeably elongated coma when looking at 10 second exposures.
• comet was moving directly left over time. This was easily noticed from successive 10 second subs
• this means the sun direction is oriented downward.

A very short view is captured here to avoid cometary distortion and motion compared to the background stars.
