364P = 2013 CU129 = 2018 A2
An asteroid was discovered by Pan-STARRS 1 with the 1.8m R-C telescope on 13
February 2013. Subsequent observations in June 2013 showed cometary features.
The comet makes relatively frequent approaches to both Jupiter and the Earth, with
approaches to our planet in 2018 (0.45 au) and 2023 (0.12 au).
Erwin Schwab reported the recovery of 2013 CU129 to the Central Bureau in
remotely obtained images that he had taken with the 0.8m Schmidt at Calar Alto,
Spain, on 16 January 2018. In the meantime Gareth Williams of the Minor Planet
Centre had identified the comet in incidental astrometry from Mt Lemmon on 12
January 2018.
