SUPERNOVA 2000fb IN ESO 205-G11
     R. Chassagne, Ste. Clotilde, Ile de Reunion, reports his
discovery of an apparent supernova (mag 15.8) on CCD images taken
with an automated 0.30-m telescope on Nov. 29.96 and 30.01, and on
Dec. 1.50 and 3.86 UT.  SN 2000fb is located at R.A. = 5h57m41s.95,
Decl. = -51o57'48".0 (equinox 2000.0), which is 6" east and 17"
north of the center of ESO 205-G11.  Nothing appears at this
position on an image taken by Chassagne on Nov. 10.01 (limiting mag
18) or on the Digital Sky Survey image taken on 1978 Jan. 12
(limiting mag 22).


SUNGRAZING COMETS
     Further to IAUC 7534, D. Hammer reports his measurements for
several additional sungrazing comets found by X. Leprette (1997
comets) and by M. Oates (remaining comets) on SOHO website images
obtained with the C2 coronagraph.  The reduced observations and
orbital elements by B. G. Marsden are given on the MPECs cited below.
