W. Kloehr, Schweinfurt, Germany, reports his discovery of a variable star (red mag about 15.2) on unfiltered CCD exposures taken on Dec. 16.16 UT with a Meade 0.25-m Schmidt-Cassegrain DSI-Pro II telescope. The new object is located at R.A. = 5h57m18s, Decl. = +68o32'26" (equinox 2000.0); nothing appears at this location on an image by Kloehr taken on Nov. 27 (limiting mag about 18), though a USNO-B1.0 star of red mag 19.2 appears at this location on a Palomar Sky Survey image. Kloehr adds that confirming CCD images of the variable were obtained by K. Torii (location unknown, 0.36-m telescope, Dec. 17.57, I_c = 15.2), and H. Maehara (location unknown, Dec. 17.63, V = 14.95, B = 15.11), and O. Trontal (Oslo, Norway, 0.35-m reflector, Dec. 17.85, unfiltered red mag about 15.2). Kloehr also relays that D. Boyd (West Challow, U.K.) observed the object for 2 hr via unfiltered CCD photometry (0.35-m Schmidt-Cassegrain reflector), revealing superhump-like modulations with a mean magnitude approximately 14.85, an amplitude of 0.2 mag and a period (via Peranso) of 0.052 ± 0.007 day – suggesting that it is an SU UMa-type dwarf nova.
