                          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.
