99P/Kowal, also known as Kowal 1, is a periodic comet in the Solar System that orbits out by Jupiter and has a 15 year orbital period. It has been observed regularly since 2019. Its most recent perihelion occurred in April 2022, and is expected to return by May 2037.Template:R
Observational history
Charles T. Kowal discovered this comet shortly after reporting the discovery of asteroid 2063 Bacchus (then known as 1977 HB) on the night of 24 April 1977.Template:R It already passed perihelion when it was first spotted as a 16th-magnitude object within the constellation Virgo.Template:R Orbital calculations by Shuichi Nakano and Brian G. Marsden predicted that the comet has a 15-year orbit around the Sun, and was expected to return by 1992.Template:R It was successfully recovered by James V. Scotti from the Kitt Peak Observatory's Spacewatch program on 21 February 1991.Template:R
Between 12 and 14 May 2021, a small outburst temporarily brightened Comet Kowal 1, which raised its apparent magnitude from 18.32 to 17.6.Template:R
