SUPERNOVA 2002cq IN ANONYMOUS GALAXY
     W. M. Wood-Vasey, G. Aldering, P. Nugent, and R. Rudas,
Lawrence Berkeley National Laboratory, report the discovery of an
apparent supernova (mag 19.2) on an unfiltered image taken on Apr.
20.3 UT with the 1.2-m Schmidt telescope at Palomar in a joint
collaboration with the NEAT program (E. F. Helin, S. Pravdo, M.
Hicks, and K. Lawrence, Jet Propulsion Laboratory).  The object
retained the same brightness on additional images taken on Apr.
29.2.  SN 2002cq is located at R.A. = 12h38m40s.43, Decl. =
-2 58'13".4 (equinox J2000.0), which is 15" south and 10" west of
the apparent host galaxy.  Nothing is visible at this location on
images from Mar. 21 and Apr. 3 (limiting mag 20).


XTE J0929-314
     R. A. Remillard, Massachusetts Institute of Technology (MIT),
for the RXTE ASM Team at MIT and Goddard Space Flight Center,
reports the discovery of a faint x-ray transient at R.A. = 9h29m22s,
Decl. = -31o22'.8 (equinox J2000.0; estimated uncertainty 3', 90-
percent confidence).  The source is visible in sky maps computed
from 6-day intervals of ASM data.  Average fluxes (2-12 keV):  Apr.
13-18, 15 +/- 2 mCrab; Apr. 19-24, 20 +/- 2; Apr. 25-30, 26 +/- 1.
The error circle contains no noteworthy sources in the Simbad
catalogues.  The ASM hardness ratios suggest an x-ray spectrum
similar to transients associated with weakly magnetic neutron stars
or some blackhole systems.  Optical and radio observations are
encouraged.
