SUPERNOVA 2004ci IN NGC 5980
     Further to IAUC 8349, M. Armstrong reports his discovery, on
images taken on June 16.997 UT, of an apparent supernova (mag 17.5)
located at R.A. = 15h41m29s.83, Decl. = +15o47'13".1 (equinox
2000.0), which is 10".1 west and 2".3 south of the center of NGC
5980.  Nothing was visible at this location on an image taken by
Armstrong on 2003 Apr. 8.  Further to IAUC 8345 and 8350, S. Park
and R. J. Foley also report LOSS observations of SN 2004ci via KAIT
images taken on June 15.3 (mag about 17.7) and 17.3 (mag about
17.4), giving position end figures 29s.71, 12".7.  A KAIT image
taken on June 12.4 showed nothing at this position (limiting mag
about 19.0).


COMETS C/2003 X5-X11 AND Y2-Y10 (SOHO)
     Further to IAUC 8356, K. Battams reports measurements for
additional Kreutz sungrazing comets found on SOHO website C2 images
by M. Boschat (C/2003 X5, X7, Y5, Y8), X.-m. Zhou (C/2003 X6, X9,
X11), T. Hoffman (C/2003 X8), X. Leprette (C/2003 X10, Y2), R.
Matson (2003 Y3, Y9, Y10), R. Kracht (C/2003 Y4, Y7), and J. Sachs
(C/2003 Y6).  C/2003 Y6 and Y7 were also visible on C3 images.  The
reductions by B. G. Marsden (and by R. Kisala for C/2003 Y8, Y9,
Y10) and orbital elements by Marsden appear on the MPECs cited
below.
