VARIABLE STAR IN PEGASUS
     Editor's note:  This replaces the text on CBET 1965
     J. Newton, Portal, AZ, U.S.A.; R. Gagliano, Cottonwood, AZ, U.S.A.; and
T. Puckett, Ellijay, GA, U.S.A., report the discovery of an possible supernova
(mag 16.4) on unfiltered CCD images (limiting mag 18.8) taken with a 0.40-m
reflector at Portal on Sept. 22.21 UT in the course of the Puckett Observatory
Supernova Search.  The new object, which was confirmed at mag 18.1 on images
(limiting mag 20.5) taken by T. Orff on Sept. 28.08 with a 0.60-m reflector at
Ellijay, is located at R.A. = 22h39m58s.36, Decl. = +34o23'05".5 (equinox
2000.0), which is 158" east and 17" north of the center of MCG +06-49-68.
Nothing is visible at this position on images taken by Puckett on 2007 Aug. 7
(limiting mag 19.6).  Following posting on the Central Bureau's unconfirmed-
objects webpage, D. Chestnov (Moscow, Russia) reports that he obtained CCD
images remotely with a 0.36-m reflector at Tzec Maun observatory (near
Mayhill, NM, U.S.A.) on Oct. 10 that yield magnitudes R = 18.6 (Oct. 10.258)
and V = 17.9 (Oct. 10.263), with position end figures 58s.43, 06".2, adding
that nothing is visible at this position on a Palomar Sky Survey (DSS) image
(limiting red mag 20.5).
     The variable was also independently discovered by S. B. Cenko, W. Li, and
A. V. Filippenko in the course of the Lick Observatory Supernova Survey,
speculating that may be a cataclysmic variable due to its sharp rise and
lack of a host in its immediate vicinity.  They report the position as R.A. =
22h39m58s.37, Decl. = +34d23'06".0, which is 159" east and 17" north of the
nucleus of MCG +06-49-68.  Available unfiltered KAIT magnitudes for the
varaible:  Sept. 18.28 UT, [19.1; 23.28, 17.2; 24.26, 17.3.  A faint object
(identified as a star) is detected in Sloan Digital Sky Survey images at this
position with the following magnitudes:  u' = 25.41, g' = 22.44, r' = 22.54,
z' = 22.36.
