     Further to IAUC 8053, W. M. Wood-Vasey, G. Aldering, and P.
Nugent report the discovery of an apparent supernova (mag 18.2) on
unfiltered NEAT images taken with the Palomar 1.2-m Schmidt
telescope on Jan. 16.16, 16.18, and 16.20 UT, with confirming
images from Jan. 25 showing the new object at mag 18.4.  SN 2003V
is located at R.A. = 3h05m43s.05, Decl. = -1 24'12".8 (equinox
2000.0).  This is 3" west and 2" north of the center of the
apparent host galaxy.  No point source is visible at this location
in previous Palomar NEAT images taken on 2002 Dec. 7, 10, 12, and
13 (subtracted against earlier NEAT images from 2001 and 2002;
limiting mag of 22.2 at S/N of 3).

     K. Nakanishi and M. Saito, Nobeyama Radio Observatory,
National Astronomical Observatory of Japan; R. S. Furuya, Istituto
Nazionale di Astrofisica, Osservatorio Astrofisico di Arcetri; H.
Shinnaga, Harvard-Smithsonian Center for Astrophysics; and M.
Momose, Ibaraki University, report on follow-up observations of the
radio flaring object in Orion cluster, using the Nobeyama
Millimeter Array (NMA) at Nobeyama Radio Observatory:  The object
is located at R.A. = 5h35m11s.79, Decl. = -5 21'49".2 (equinox
2000.0; estimated uncertainty 0".2), which agrees well with that
reported on IAUC 8055.  The NMA data give continuum flux densities
of 39.1 +/- 5.1 mJy at 146.969 GHz on Jan. 25.55 UT (resolution
1".3 x 0".9) and 22.4 +/- 5.4 mJy at 97.782 GHz on Jan. 25.62
(resolution 2".5 x 1".2).  We suggest that the object is/are (a)
massive (proto)star(s) that might be involved in mass-ejection
event(s). Further interferometric observations at millimeter
wavelengths are planned, and observations at other wavelengths are
urgently requested."

     R. J. Foley, J. Graham, M. Ganeshalingam, and A. V. Filippenko,
University of California, Berkeley, report that inspection of CCD
spectra (range 310-1000 nm), obtained on Jan. 28 UT with the Shane
3-m telescope at Lick Observatory, reveals that SN 2003P (IAUC 8057)
is of type Ia, roughly 1 month past maximum brightness.  SN 2003T
(IAUC 8058) is of type II, perhaps a week after the explosion;
hydrogen Balmer lines with P-Cyg profiles are superposed on a blue
continuum, but the emission component of H-alpha greatly dominates
over the absorption component.
