SUPERNOVA 2000cq IN UGC 10354
     W. D. Li, University of California at Berkeley, on behalf of
the Lick Observatory Supernova Search (cf. IAUC 6627, 7126),
reports the discovery with the 0.8-m Katzman Automatic Imaging
Telescope (KAIT) of an apparent supernova on unfiltered images
taken on June 23.3 UT, with confirmation images taken taken on June
24.3 (limiting mag about 20.5) and 25.3 (limiting mag about 21.5),
all showing the new object at mag about 19.3.  SN 2000cq -- which
also showed a hint of presence in images taken on May 30, June 2,
11, 15, and 20 -- is located at R.A. = 16h21m21s.34, Decl. =
+40o48'09".7 (equinox 2000.0), which is 7".8 west and 28".6 south
of the nucleus of UGC 10354.  KAIT images of the same field taken
on May 3.3 and 9.3 (all with limiting mag about 20.0) showed
nothing at the position of the supernova, and there is no
indication of SN 2000cq on the second Palomar Sky Survey blue
(1989) and red (1993) images (limiting mag about 22.0).


SUPERNOVA 2000cp IN PGC 57064
     S. Jha, P. Challis, and R. Kirshner, Harvard-Smithsonian
Center for Astrophysics, report that a spectrum of SN 2000cp (cf.
IAUC 7441), obtained by P. Berlind on June 22.28 UT with the F. L.
Whipple Observatory 1.5-m telescope (+ FAST spectrograph), shows it
to be a type-Ia supernova at maximum light.  Narrow superimposed
H-alpha emission yields a recession velocity of 10 260 km/s for the
host galaxy.  The expansion velocities of the Ca II H and K and the
Si II (rest 635.5 nm) features are 16 400 and 11 400 km/s,
respectively.  The spectral-feature age of the supernova (Riess et
al. 1997, A.J. 114, 722) is 1 +/- 3 days before maximum light.


AX J0049.4-7323
     M. Ueno, J. Yokogawa, K. Imanishi, and K. Koyama, Kyoto
University, communicate:  "An ASCA observation made during Apr. 11-17
revealed coherent pulsations of period 755.5 +/- 0.6 s from a new
source in the Small Magellanic Cloud, designated AX J0049.4-7323
and located at R.A. = 0h49m25s.2, Decl. = -73o23'17" (equinox
2000.0; error radius 1'.5).  The spectrum is characterized by a
flat power-law function with photon index 0.7 and x-ray flux 1.1 x
10**-12 erg cm**-2 s**-1 (0.7-10 keV).  The Be/x-ray binary RX
J0049.7-7323 (Haberl and Sasaki 2000,
http://xxx.lanl.gov/abs/astro-ph/?0005226) is located within the
ASCA error region."
