Description

Imaged Comets C/2022 E3 (ZTF) and C/2022 U2 (ATLAS) on the night of February 6, 2023.   ZTF was far, far brighter than ATLAS which is barely discernable as a faint green smudge below ZTF in this image.  ZTF's green coma and dust tail are still nicely visible, but it's ion tail is no longer visible in this image.
