SUPERNOVA 2004fd IN NGC 1060
     Further to IAUC 8417, T. Boles reports his discovery of an
apparent supernova (mag 15.7) on unfiltered CCD images taken on
Oct. 21.835 and 24.840 UT.  The new object is located at R.A. =
2h43m15s.25, Decl. = +32o25'25".6, which is approximately 2".5 east
and 4".3 south of the center of NGC 1060.  SN 2004fd is not present
on Boles' images from Aug. 25, Sept. 8, and Oct. 5 (limiting mag
19.5) or on a Quick-V survey plate from 1982 (limiting mag 19.0).

     N. M. Ashok and D. P. K. Banerjee, Physical Research
Laboratory, Ahmedabad, report the following near-infared magnitudes
of V838 Mon, obtained following conjunction with the sun, using the
1.2-m Mt. Abu telescope:  Oct. 4.021 UT, J = 7.50, H = 6.19, K =
5.52 (typical errors 0.05 mag).  For comparison, magnitudes on Mar.
9.646 were J = 7.14, H = 5.96, and K = 5.3.  Spectra (range 1.08-
2.35 microns) obtained on Oct. 4 are reasonably similar to spectra
taken earlier in 2004.  The (1,0) and (4,0) A-X bands of AlO are
prominently seen along with the deep absorption in the first-
overtone band of CO at 2.29 microns.  In addition, several second-
overtone bands of CO (starting from the 3-0 to the 10-7 transition)
are also seen in the H band.

COMET C/2004 U2 (SOHO)
     Further to IAUC 8419, another SOHO comet found on C3
coronagraph images, this time by H. Otterstedt ('discovery'
observation below), which K. Battams has found to have peaked near
mag 7 before rapidly fading over the two-day arc of observation.
The astrometry (measured by Battams, reduced by B. G. Marsden),
orbital elements by Marsden (T = Oct. 18.0 TT, q = 0.066 AU, i = 84
deg), and an ephemeris appear on MPEC 2004-U26.

     2004 UT           R.A. (2000) Decl.
     Oct. 16.596      13 51.5      - 6 45

     Total-magnitude and coma-diameter estimates:  Sept. 16.70 UT,
9.9, 2' (S. T. Rae, Hamilton, New Zealand, 0.20-m reflector); Oct.
11.71, 8.8, 3'.5 (K. Yoshimoto, Yamaguchi, Japan, 20x100
binoculars); 22.82, 7.7, 7' (A. Pearce, Noble Falls, W. Australia,
8x40 binoculars).
