Comet C/2021 C4 (ATLAS) was about magnitude 18 and 341 million miles from Earth in this image taken above the light pollution and haze of Tucson as it was located low above the southern horizon. The comet has a faint tail to the SSE of the coma. The comet was at perihelion in its orbit this past January and will stay around magnitude 18 for the next few months before slowly fading as it moves away from Earth.

Comet 152P/Helin-Lawrence now has a very faint slim 0.012 degree long tail pointing WNW of the coma which isn't bad for such a faint comet. In these images the comet is only magnitude 19.3 and is 288 million miles from Earth. 152P will reach perihelion in its 9.48 year orbit in January 2022 but it won't brighten to magnitude 16 until the summer of 2022.
