Nishimura’s billowing tail


Allen Hwang from Deming, New Mexico

Comet Nishimura (C/2023 P1) continues to impress, seen here the morning of Wednesday, Sept. 6. The wavy structures visible in its ion tail are evidence of its interactions with the Sun’s wind of charged particles. The imager took this with a Celestron 11-inch RASA f/2.2 and a ZWO ASI6200MC Pro camera, stacking seven 30-second frames obtained between 5:33 and 5:37 A.M. MDT.
