Skiff, Lowell Observatory, reports the discovery of a comet by the LONEOS program. Confirming CCD images by L. Wasserman (1.07-m Lowell Observatory telescope) show a coma diameter of about 9" and a tail about 14" long toward the southwest. 2000 UT R.A.

Clocchiatti, Pontificia Universidad Catolica de Chile (PUC), on behalf of the PUC-Padova Supernova Search, reports the discovery of a supernova (V = 22.9) on three images taken on Dec. 17.3 UT with the 2.2-m telescope (+ WFI) at ESO, La Silla. SN 2000fp is located at R.A. = 5h38m01s.27, Decl. = -23o46'34".1 (2000), which is 3".2 south and 2".9 west of the host galaxy's nucleus. IAUC 7549 (extract) SUPERNOVA 2000fq D. M. Wittman et.al., report the discovery of a supernova (R about 23.8) in a series of five R-band images taken on Dec. 21.4 UT with the 4-m Mayall telescope at Kitt Peak; the images were differenced with deeper (limiting R mag 26) images taken one year ago using the same instrumentation. SN 2000fq is located at R.A. = 9h23m37s.68, Decl. = +29o52'26".0 (2000), which is > 5" from the nearest member of a group of galaxies (R about 20). IAUC 7551 (extract) POSSIBLE NOVA IN PUPPIS T. Kato, Kyoto University, reports the discovery by Kazuyoshi Kanatsu (Matsue, Shimane, Japan) on his T-Max 400 film exposures of a new variable star at R.A. = 7h37m58s, Decl. = -25o56'51" (2000). Kanatsu finds no apparent counterpart on the Digital Sky Survey. K. Takamizawa (Saku-machi, Nagano) reports that the new object was not present on 22 T-Max 400 exposures (limiting mag 14) taken by himself between between 1994 Mar. 14 and 1999 Dec. 3; he notes the presence of a close stellar companion of mag 14.5, which is apparently a red star (red mag 13.6) in the USNO A2.0 catalogue having position end figures 58s.43, 46".8. Available magnitudes: 2000 Jan. 15.72 UT, [11.7 (Kanatsu; T-Max 400); Nov. 28.703, 8.6 (Takamizawa; T-Max 400); Dec. 22.578, 8.8 (Takamizawa); 22.731, 8.7 (Kanatsu); 30.585, 8.8 (A. Takao, Kitakyushu, Fukuoka, Japan; unfiltered CCD); 30.612, 9.2 (R. Stubbings, Drouin, Victoria, Australia; visual). IAUC 7552 Guy M Hurst
