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.
