Comet Chasing in June


Comet chasing is the visual observation of telescopic comets.  Jump to:  Observing synopses    Summary data

News


There is one comet visible in small telescopes this month. Many more are visible in larger instruments.
  • C/2021 O3 (PANSTARRS) passed perihelion on April 21. In early May this comet will pass within 0.6 AU of the earth. It reached maximum brightness of magnitude in late April. 

  • 45P/Honda-Mrkos-Pajdusakova was only recently recovered. It passed perhilion on April 26, and was not seen prior. 

  • C/2019 T4 (ATLAS) will reach perihelion in early June of 2022. It is currently predicted to reach maximum brightness of magnitude 12.2 in late May.

  • C/2021 E3 (ZTF) will reach perihelion in mid June of 2022. It is predicted to reach maximum brightness of magnitude 10.5 in early June.

  • C/2021 P4 (ATLAS) will reach perihelion at the end of Junly 2022. It is predicted to reach maximum brightness of magnitude 9 in late July..

  • C/2017 K2 (PANSTARRS) passed perihelion in mid December 2022. 

  • C/2019 L3 (ATLAS) passed perihelion on January 9.

  • 19P/Borrelly passed perihelion in early February and is fading.

  • 104P/Kowal reached perihelion in mid January 2022.

  • 67P/Churyumov-Gerasimenko passed perihelion in early November. On November 2 this comet passed within 0.4 AU of the earth.

  • C/2021 A1 (Leonard) was discovered on January 3, 2021 by by G. J. Leonard at Mount Lemmon Observatory. It passed perihelion on January 3, 2022. 

  • 29P/Schwassmann-Wachmann has frequent outbursts, typically resulting in a brightening of 0.5 - 1.0 magnitudes, which occur roughly every 59 days, typically taking 5-10 days to subside. Up to three subsequent outbursts may occur 5-10 days afterward, each typically smaller than the last, although on some occasions they can be even brighter than the first. These outbursts make 29P one of the most interesting comets to follow, both visually and scientifically. 29P/Schwassmann-Wachmann has a 14.8-year orbital period, and last passed perihelion in early March 2019. It varies in its distance from the Sun from 5.8 AU (at perihelion) to 6.3 AU (at aphelion), which is an unusually small variation for a comet, and remains quite far from the sun at all times. This means that it can be observed more or less continuously.

  • C/2014 UN271 (Bernardinelli-Bernstein) is an interesting Oort cloud comet that was recently reported as a result of the Dark Energy Survey. Soon after it was made public, images showed a cometary coma. Discovery credit goes to Pedro Bernardinelli and Gary Bernstein. This is a remarkable comet that was at 29 AU in 2014, with a perihelion of 10.9 AU in 2031. Its orbit extends out to 40,000 AU! It was unusually bright for its distance. Recent HST obsrvations that isolate the nucleus estimate the diamter to br between 120 and 140 km, making this possibly the largest comet nucleus yet measured. Because of its distant perihelion, this comet is not expected to become bright enough to be visually observed except in large instruments, and not until the end of the decade, but it is likely going to be the subject of intense scientific scrutiny. 

Comets that have apparently disentegrated: C/2020 Q1 (Borisov), C/2020 P1 (NEOWISE), and C/2019 Y4 (ATLAS). Beware that various other online sources often fail to keep track of whether or not a comet still exists!

Comet Visibility in the Eyepiece

This page uses code developed for SkyTools to predict the visibility of a comet in the eyepiece.  Predicting how much aperture is required to see a comet is a very complex task.  Have a look for yourself: a comparison of the predictions below (such as "visible in small telescopes") to the magnitude of each comet shows just how poor an indicator the magnitude alone really is. When you read below that a particular aperture is required to see a comet you can have a reasonable degree of confidence that the comet can in fact be seen in the eyepiece. But always remember, comets are like cats. They both have tails and do what they want, and not always what we expect. This is one of the things that makes comet chasing interesting!
