PK06F010 = 0391P R Kowalski discovered an 18th magnitude comet on 21 March 2006 during the course of the Mt Lemmon survey with the 1.5-m reflector. The initial orbit suggested that it would reach perihelion at 1.9 AU in May 2007, when it might reach 13th magnitude. Further observations showed that it is in a periodic orbit, as first suggested by Hirohisa Sato. The comet appears to have had a recent close encounter with Jupiter. The comet was recovered by Kevin Hills as reported in 2019 U2 on 26 October 2019.
