The best site for up-to-date comet viewing information is Dominic Ford’s comet site www.in-the-sky.org. Any pictures/links are used with permission. Go to his comets page for a table of comets sorted by magnitude. Finder charts can also be found through this page.
Comet Leonard disintegrated as it passed the Sun, so there will be no return to our skies for a repeat. Other comets listed on www.in-the-sky.org brighter that 10th or 11th magnitude are technically visible in binoculars or telescopes. No comets brighter than 9th magnitude are in the sky presently. C/2017 K2 appears to be a possibility for a binocular object later this summer. See this comet's magnitude graph at the bottom of this page. Comet C/2021 O3 PanSTARRS has appeared on the scene but has not brightened as expected and is now fading.
The plot below from www.aerith.net shows the magnitude (brightness) of C/2017 K2. The apparent magnitude is plotted vertically and date horizontally, with observers' estimates indicated as dots.
