SUPERNOVA 2002kj
     Further to IAUC 8027, W. M. Wood-Vasey, G. Aldering, P. Nugent,
and K. Li report the discovery of an apparent supernova (mag 18.5)
on unfiltered NEAT images (cf. IAUC 8029) taken with the Haleakala
1.2-m telescope on 2002 Dec. 1.35, 1.36, and 1.37 UT.  Confirming
images were obtained with the same telescope on Dec. 17, showing
the new object at mag 18.9.  SN 2002kj is located at R.A. =
0h35m24s.73, Decl. = +3 59'11".4 (equinox 2000.0), which is 1".6
west of the center of the apparent host galaxy.  No point source is
visible at this location in previous NEAT images taken on 2001 Aug.
14, Sept. 17, Oct. 6, Nov. 9, 2002 Oct. 28, 29, and Nov. 2, to
limiting mag 21.0 (S/N = 3).


COMETS C/2001 RX_14 (LINEAR) AND C/2002 V1 (NEAT)
     M. Honda, University of Tokyo, and colleagues (T. Yamashita,
H. Kataza, T. Miyata, T. Fujiyoshi, S. Sako, Y. K. Okamoto, T.
Onaka, T. Sekiguchi, D. Kinoshita, and J. Watanabe) report on mid-
infrared observations of two comets with the 8.2-m Subaru Telescope
(+ COMICS).  N/Q-band imaging of C/2002 V1 on Jan. 11.2 UT yield
the following total fluxes within a 2".73-box aperture:  8.8
microns, 0.83 +/- 0.01 Jy; 11.7 microns, 1.55 +/- 0.02 Jy; 12.4
microns, 1.95 +/- 0.04 Jy; 18.8 microns, 2.79 +/- 0.06 Jy.  Low-
resolution (250) N-band spectroscopic observations (range 8-13
microns) of C/2002 V1 showed a broad amorphous silicate feature
with a 11.2-micron local peak, indicating the presence of
crystalline olivine.  Total fluxes for C/2001 RX_14 on Jan. 11.6
(measured as above):  8.8 microns, 0.066 +/- 0.004 Jy; 12.4 microns,
0.279 +/- 0.016 Jy; 18.8 microns, 0.356 +/- 0.022 Jy.  Low-
resolution N-band spectroscopy of C/2001 RX_14 showed the possible
shallow silicate feature, but no 11.2-micron local peak was found
within the error bars.
