I’ve got some good news and some bad news. First the good news. Oodles of comets are on their way in 2021. Now the bad. Most won’t get brighter than 9th magnitude with the possible exception of Comet Leonard (C/2021 A1), a recent discovery that could rise to naked-eye visibility in December.

While waiting for Leonard to take the stage we’ll have a steady stream of returning periodic comets plus new finds made by the ATLAS survey and NASA’s NEOWISE
