     The Minor Planet Electronic Circulars contain information on unusual
         minor planets and routine data on comets.  They are published
    on behalf of Division F of the International Astronomical Union by the
          Minor Planet Center, Smithsonian Astrophysical Observatory,

                     COMET P/2005 Y2 = 2019 E2 (McNaught)

     This comet has been recovered by E. Schwab (J04), who described the object
as showing no coma or tail in stacked images with a total exposure of 600s.
L. Kurtze (F65) reported confirmation images, again showing no coma or tail
in stacked images with a total exposure of 540s.  The indicated delta-T
correction to the prediction, by the undersigned, on MPC 75706 is +0.04 days.
