comet
in the
Solar System
with a current orbital period of 8.19 years.

The comet was discovered on a photographic plate on 20 September 1936 by Cyril Jackson of the
Union Observatory
, South Africa, who described it as faint and diffuse, with a brightness of magnitude 12. On the following day
Grigory N. Neujmin
of the
Simeis Observatory
in
Crimea
discovered it independently.
Fernand Rigaux
of the
Royal Observatory
in Uccle, Belgium then also found it on an earlier photographic plate exposed on 9 September 1936.
The predicted 1945 apparition was not observed due to uncertainty about its position and appearance date and even
Elizabeth Roemer
was unable to find it in 1953. 1961 was again very difficult but
Charles Kowal
managed to relocate it in September, 1970. The 1995 appearance was more favourable and brightness reached a magnitude of 10. The comet wasn't observed during its 2004 or 2012 apparitions, and was thought to be potentially lost until it was successfully recovered in April 2020 at magnitude 12 by the Solar Wind Anisotropies (SWAN) camera on the
Solar Heliospheric Observer (SOHO)
spacecraft.

Due to an outburst event the magnitude increased from 12 to 10 in late March 2020.
