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. For

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 charthttp://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. (C) Copyright 1999 CBAT 1999 July 5 (7214) Daniel W. E. Green
