COMET 2000 Y2
     B. Skiff, Lowell Observatory, reports the discovery of a comet
by the LONEOS program.  Confirming CCD images by L. Wasserman
(1.07-m Lowell Observatory telescope) show a coma diameter of about
9" and a tail about 14" long toward the southwest.

SUPERNOVA 2000fp IN ANONYMOUS GALAXY
     A. Clocchiatti, Pontificia Universidad Catolica de Chile
(PUC), on behalf of the PUC-Padova Supernova Search (cf. IAUC 7537;
including P. Arevalo, C. Rada, F. Barrientos, D. Minniti, and F.
Courbin, PUC; M. Turatto, G. Altavilla, S. Benetti, E. Cappellaro,
and A. Pastorello, Osservatorio di Padova; and B. Leibundgut and J.
Spyromilio, European Southern Observatory), reports the discovery
of a supernova (V = 22.9) on three images taken on Dec. 17.3 UT
with the 2.2-m telescope (+ WFI) at ESO, La Silla.  SN 2000fp is
located at R.A. = 5h38m01s.27, Decl. = -23o46'34".1 (equinox
2000.0), which is 3".2 south and 2".9 west of the host galaxy's
nucleus.  No object appears at this location on images taken on
Nov. 17.24.  A spectrum (range 333-747 nm, resolution 1.6 nm) with
low signal-to-noise ratio, obtained on Dec. 22.24 with the ESO 3.6-
m telescope (+ EFOSC2), shows a relatively blue continuum with few
broad absorption features, two of which match H-beta and H-gamma
once the spectrum is blueshifted to the parent galaxy rest frame (z
= 0.30, from several narrow absorption features in a separate
spectrum).  SN 2000fp appears to be of type II, close to maximum.
