"This is usually in the form of water-ice. COMET 19P/BORRELLY       (Perihelion 2022 February 1). In the Northern Hemisphere, it stays observable in excellent condition for a long time. In the Northern Hemisphere, it is not observable until 2022. Express. It stays 14-15 mag until 2021. In the Southern Hemisphere, it will be low in December. 435) I missed this comet entirely during its unfavorable return in 2015, although apparently some observers in the southern hemisphere managed to detect it as a faint object. By this point during the 1999 return, which was quite similar geometrically to this year's (with a one-week difference in respective perihelion dates), I had already picked it up visually, so at the very least the comet is significantly fainter intrinsically now than it was then, and it is conceivable that it has disintegrated within the recent past. In the Southern Hemisphere, it stays extremely low until spring. However, experts are unsure if the comet will remain until May 12. It was expected to brighten very rapidly, and brighten up to 11 mag from December to January. Please see our Privacy Notice for details of your data protection rights. Even more unfortunately, the comet is on the far side of the sun from Earth at the time, never coming closer than 2.23 AU. Now it is 16.3 mag (Nov. 14, Y. Sugiyama). In the Northern Hemisphere, appearing in the morning sky. 35 deg in the Northern Hemisphere. It has already faded down to 15.7 mag (Nov. 12, Toshihiko Ikemura, Hirohisa Sato). Now it is fading. Now it is 18.1 mag (Nov. 20, Toshihiko Ikemura, Hirohisa Sato). LONG-RANGE COMETS . In the Southern Hemisphere, it is not observable now. It locates very low in the Northern Hemisphere. It could not be detected as fainter than 18.0 mag on June 30 (Charles S. Morris), and fainter than 15.7 mag on July 13 (Sandor Szabo). It brightened up to 14.6 mag in summer (July 18, Thomas Lehmann). In 2021, it is observable at 15-16 mag in good condition. Now it is 14.0 mag (Nov. 11, Toshihiko Ikemura, Hirohisa Sato). It has already faded down to 16.5 mag (Nov. 8, Toshihiko Ikemura, Hirohisa Sato). New Zealand resident John Drummond told Space Weather: "Hi, I just came in from observing C/2020 F8 with the naked eye (2020 Apr 29 UT). Visibility from selected location = visible to the naked eye = binocular, brighter than 10th magnitude = current altitude ≥ 30° = current altitude < 30° = below the horizon Location: Greenwich, United Kingdom . 35 deg in the Northern Hemisphere. In the Northern Hemisphere, it is not observable until June in 2021. Now it is 13.9 mag (Nov. 9, Toshihiko Ikemura, Hirohisa Sato). After the comet becomes accessible in the morning sky early next year I am reasonably confident I will be able to detect it visually at that time. In the Southern Hemipshere, it will never be observable again. It will approach to Sun down to 0.14 a.u. In the Northern Hemisphere, it is not observable at the high light from 2022 summer to 2023 summer. It will brighten up to 13 mag in 2022. Now it is 14.8 mag (May 14, Toshiyuki Takahashi). Now it is 15.9 mag (Nov. 10, Toshihiko Ikemura, Hirohisa Sato). Now it is 17.4 mag (Nov. 8, Toshihiko Ikemura, Hirohisa Sato). DON'T MISSAsteroid discovery: 'Oumuamua was part of larger bodyComet ATLAS 2020: Comet Y4 breaking up as it approaches the SunComet ATLAS: Comet could be as bright as the MOON as it nears the Sun, He continued: "I doubt that the comet will maintain its current impressive appearance, and will quite possibly fade away soon. Now it is 15.1 mag (Nov. 9, Toshihiko Ikemura, Hirohisa Sato). "That is, some major eruption happened to this otherwise small and faint comet, releasing a massive cloud of hydrogen-rich volatiles. Based upon the reported brightnesses in 1956, the comet should reach a peak brightness between 6th and 7th magnitude. Karl Battams of the Naval Research Lab in Washington DC said: "For SWAN to see a comet, it means the comet must be producing a fairly significant amount of hydrogen. It stays observable at 17 mag in good condition from summer to winter. It approaches to Earth down to 0.5 a.u. Now it is 16.4 mag (Nov. 9, Toshihiko Ikemura, Hirohisa Sato). Now it is 16.0 mag (Nov. 10, Toshihiko Ikemura, Hirohisa Sato). Now it is 11.2 mag (Sept. 11, Carlos Labordena). Now it is 17.1 mag (Oct. 25, D. Buczynski). COMET 7P/PONS-WINNECKE       (Perihelion 2021 May 27). It stays 15-16 mag for a long time until 2021. I plan to update this page every one to two months and/or as necessary. Now it is 14.3 mag (Nov. 5, Sandor Szabo). It stays observable in the evening low sky after this while it will be getting fainter gradually. Awesome to see a naked eye comet again!". It is expected to brighten up to 15-16 mag from February to March, and it will be observable in good condition. The viewing geometry in 2024 is, unfortunately, rather unfavorable, as during the run-up to perihelion the comet remains on the far side of the sun from Earth and is only visible for a brief period of time in the northwestern sky after dusk, at a small elongation (37 degrees in mid-March, shrinking to 28 degrees by month's end and to 23 degrees by perihelion).
