Schwartz, Cottage Grove, OR, reports his discovery of an apparent supernova (mag 16.1) on an unfiltered CCD frame taken on Jan. 23.23 UT utilizing the Tenagra I 0.35-m automated supernova patrol telescope in Sonoita, AZ, internet-controlled from Cottage Grove. SN 1999X is located at R.A. = 8h54m32s.23, Decl. = +36o30'41".1 (2000), which is about 4".1 east and 5".5 north of the nucleus of CGCG 180-22. IAUC 7105 SUPERNOVA 1999Y IN ANONYMOUS GALAXY D. Reiss, Department of Astronomy, University of Washington, reports the discovery by the Mount Stromlo Abell Cluster Supernova Search Team of an apparent supernova (V = 19.0) on V and R CCD images (limiting mag V = 21.0) taken on Jan. 10 by S.Sabine at the Mount Stromlo 1.27-m telescope (+ Macho Camera). SN 1999Y is located near Abell 3142 at: R.A. = 3h36m55s.81, Decl. =-39o33'04".9 (2000), which is 3".8 west and 0".9 south of the host galaxy's centre. IAUC 7106 SUPERNOVA 1999Z IN UGC 5608 M. Schwartz, Cottage Grove, OR, reports his discovery of an apparent supernova (mag 16.2) on an unfiltered CCD frame taken on Feb. 8.437 UT with the Tenagra I 0.35-m internet-controlled supernova patrol telescope in Sonoita, AZ. SN 1999Z is located at R.A. = 10h22m37s.23, Decl. = +27o21'19".8 (equinox 2000.0), which is about 3".6 west and 9" south of the nucleus of UGC 5608. IAUC 7106 SUPERNOVA 1999aa IN NGC 2595 Ron Arbour, South Wonston, Hants, U.K., reports his discovery of an apparent supernova (mag about 15.5) in the galaxy NGC 2595 on an unfiltered CCD image (limiting mag about 17.5) taken on Feb.11.0166 UT using a 0.3-m f/6.3 reflector in the course of his supernova patrol. M. Armstrong confirmed the new object's existence via two exposures (the first at Feb. 11.0461 UT), measuring its position as R.A. = 8h27m42s.03, Decl. = +21o29'14".8 (2000), which Arbour notes to be 1" east and 28" north of the centre of NGC 2595. Nothing is present at this position on six images taken by Arbour in 1998 Feb. and Mar. (limiting mag about 17.5), nor is it present in the Digitised Sky Survey. Arbour notes that a CCD image obtained by M. Schwartz with the Tenagra 0.35-m patrol telescope on Feb. 12.07 yields an offset of 2" east, 27" north, while an image by Schwartz obtained on 1998 Nov. 26.45 shows no object at this location. IAUC 7108 (extract) Editor: We extend our congratulations to Ron on the discovery of his third supernova. Guy M Hurst
