Hey, Space Placers!
This map shows the sky for latitude 40° north at the start of dawn about 90 minutes before sunrise for the contiguous U.S. and Canada. On September 6th Comet Nishimura stands about 10° high but dips lower each morning until it's only a few degrees above the horizon on September 11th. Its gradual decline is offset by the stars rising 4 minutes earlier each morning. More good news — the comet is bright enough to see into early twilight. Venus moves only a little during the time frame, making it — along with Epsilon (ε) Leonis (Algenubi) and Gamma (γ) Leonis (Algieba) — useful celestial guides.

Comets are like cats - you never know what they are going to do......
We have a new comet visible - with difficulty - in the pre-dawn Eastern sky.
Your best bet is a flat and if possible, elevated horizon with binoculars. The comet will switch to sunset skies in the West next week.
