Discovered early this year, Comet C/2023 H2 Lemmon may approach naked eye brightness this month.

A comet discovered earlier this year is performing above expectations, and is currently well-placed in the dusk sky. We’re talking about Comet C/2023 H2 Lemmon, moving up the charts now at magnitude +8 and brightening.

To be sure, it’s nothing more than a fuzzy patch, a binocular comet sliding through the constellation Auriga looking like a globular cluster that refuses to resolve into focus. Though E3 ZTF may not live up to the hype, it does have one thing going for it: it is currently well-placed for northern hemisphere viewers. It also put on a great show for astrophotographers as it recently completed an orbital plane-crossing, as seen from our Earthly vantage point.

Comet E3 ZTF Brightens as the First Good Comet of 2023

Comet E3 ZTF

The first good comet of the year, Comet E3 ZTF is a fine object for northern hemisphere observers in January.

As in years previous, 2023 kicks of with another decent binocular comet.

If you haven’t seen C/2022 E3 ZTF yet, you’ll soon have your chance. Discovered by the Zwicky Transient Survey searching for supernovae, E3 ZTF was first spotted as a +17th magnitude object gliding through the constellation of Aquila the Eagle on the night of March 2nd, 2022.
