Comets above magnitude 9 or so (to keep them within binocular range) are shown in the screenshot below taken from www.aerith.net.


Comet C/2020 F3 NEOWISE now rated a "GREAT COMET!"

Comet NEOWISE was a very nice naked eye comet for a few weeks and has been observed widely in the northern hemisphere. It has faded to below naked eye visibility (magnitude 5 or less) as of the beginning of August, but by all reports many saw it at it its best a few weeks ago. It is still visible in binoculars so if you have not seen it, at least give it a shot on the next clear night. All you need is a clear sky view to the northwest. It is still visible with a tail in dark skies. The finder chart below will help you locate it beneath the handle of the Big Dipper.

The magnitude graph below from www.aerith.net plots magnitude vertically and date horizontally, with observers' estimates for comet NEOWISE.


Three comets in a 10° circle August 6

As one last hurrah for this comet, it will meet up with two others in the NW sky in the first week of August. The diagram below illustrates the paths of Comet NEOWISE, Lemmon (A/2019 U6) and PanSTARRS (C/2017 T2). Note that around August 6, all three are in a 10 degree circle (positions marked with yellow dots). This is interesting from a photographic point of view as all should show up on a long exposure photo, but the visual effect will not be impressive. The brightness of the comets are NEOWISE about 5, Lemmon around 7 and PanSTARRS about 10, so only NEOWISE will be visible easily in binoculars, and possibly Lemmon; PanSTARRS will be a challenge.
