                      COMET P/2003 L1 = 2019 E1 (Scotti)

     This comet was recovered by E. Schwab (J04) in images obtained on Mar. 9
and 10.  On both nights, a ~10" tail in P.A. 300 was visible in stacked images
with a total exposure time of 600s.  The indicated delta-T correction to the
prediction, by the undersigned, on MPC 105247 is -0.39 days.
