COMET 1997 D1
     Jean Mueller reports her discovery of a comet on a plate taken
by K. M. Rykoski and J. D. Mendenhall with the 1.2-m Oschin Schmidt
telescope in the course of the second Palomar Sky Survey.  The
comet is slightly diffuse with some central condensation; no tail
is visible.  The following positions from beginnings and ends of
trails were reduced by B. G. Marsden, following measurement by J.
Mueller:

COMET P/1997 C1 (GEHRELS)
     New orbital elements for this comet (IAUC 6549, 6550),
published on MPEC 1997-D06 and MPC 29067 (and used for the
ephemeris below), show it to be of short period (P = 17 years).
