C/2023 P1 (Nishimura) 2023-Sep-03 Eliot Herman

Comet 2023 P1 (Nishimura) in Tucson AZ predawn
Vixen VSD astrograph Nikon Z7II 15 sec x 20 stacked iso 800, captured as the sky was getting brighter as the comet cleared the foothills in Tucson. Magnitude at this capture is about 6.6 +/- 0.3 per www.Cobs.si.

This comet may be the source of the Sigma Hydrids meteor shower peaking December 14th 2023, an often overlooked meteor shower since its radiant is close to the much greater Geminid meteor shower also peaking the same date.
