                          COMET P/2020 M1 (PANSTARRS)                           

     This object was reported by Y. Ramanjooloo on June 17 UT on behalf of
Pan-STARRS 1 (F51) as a possible comet, noting a very condensed 1".4 coma and
3".8 tail toward PA 228.  The object was subsequently found to be associated
with prediscovery observations taken on May 24 and 28.  Additional reports of
cometary features are as follows:
