SUPERNOVA 1999cz IN NGC 5078
A. Williams, R. Martin, and S. Woodings report their discovery
of an apparent supernova (mag about 16) on an image taken on June
21.53 UT in the course of the Perth Automated Supernova Search. A
confirming image was obtained on June 23.4, while no object was
present at this location brighter than mag about 18 on May 22.6,
and an earlier image shows no object to a limiting magnitude of
about 18.5. C. Livingston (Curtin University) and J. Biggs and A.
Verveer (Perth Observatory) provide the following position for the
supernova candidate from an unfiltered CCD image obtained around
July 1.493 with the 0.25-m Mike Candy Telescope at Perth
Observatory: R.A. = 13h19m48s.53 +/- 0s.02, Decl. = -27o24'04".5
+/- 0".2 (equinox 2000.0; mag 16.5), which is about 36" northwest
of the center of NGC 5078.
GRB 990704
A. Maury and B. Gaillard, Observatoire de la Cote d'Azur (OCA);
and M. Boer, Centre d'Etude Spatiale des Rayonnements, CESR/CNRS,
report on behalf of the OCA/CESR GRB collaboration: "We observed
the error box of GRB 990704 (R.A. = 12h19m30s, Decl. = -3 48'.2,
error-circle radius about 7'; GCN 360, 366) with the OCA 0.90-m
Schmidt telescope (+ unfiltered CCD). An object that is not
present on the Palomar Sky Survey has been detected at R.A. =
12h19m29s.29, Decl. = -3 47'25".8 at mag 19.4 on July 4.876 UT.
Since the field was very low in the sky, the position reported
here may be affected by somewhat large errors. Images of the
field and of the optical transient are available at the following
URL: http://wwwrc.obs-azur.fr/schmidt/observations/GRB990704.html.

VARIABLE STAR TOWARDS UGC 11289
M. Modjaz and W. D. Li, University of California at Berkeley,
on behalf of the Lick Observatory Supernova Search, report the
discovery with the 0.8-m Katzman Automatic Imaging Telescope (KAIT)
of a variable star in the field of UGC 11289. The possible
cataclysmic variable, discovered and confirmed on unfiltered images
taken on July 1.4 (mag about 17.8) and 2.4 UT (mag about 18.9), is
located R.A. = 18h35m56s.27, Decl. = +22o26'40".0 (equinox 2000.0;
finding chart http://astron.berkeley.edu/~bait/1999/cv_1.html). A
KAIT image of the same field on June 27.4 (limiting mag 19.0) and
25.4 (limiting mag 19.5) showed nothing at this position.
