COMET P/2014 U2 = 2019 O1 (Kowalski)
This comet has been recovered H. Sato (Q62) in images obtained on July 27
and 28 UTC. The comet was of stellar appearance, in twelve stacked 60-s
exposures, on both nights. The indicated delta-T correction to the prediction,
by the undersigned, on MPC 102108 is -0.02 days.
