      J. Skvarc, Crni Vrh Observatory, reports the discovery of a new
star-like object (mag about 15.2) on four unfiltered CCD images
(limiting mag 18.5) taken during Oct. 26.010-26.037 UT in the course
of the PIKA project at with the Crni Vrh 0.60-m f/3.3 Cichocki
telescope.  The new object is located at R.A. = 3h29m12s.26, Decl. =
+12d50'17".6 (equinox 2000.0 presumed); nothing is visible at this
location on Crni Vrh archival images taken on 2004 Sept. 10, Nov. 16,
and 2005 Jan. 22 (limiting mag 18.5) or on several Palomar Sky Survey
and 2MASS images from the Aladin database.  Confirming unfiltered CCD
images were taken with a 0.40-m f/3.6 telescope by R. Palcic at Rezman
Observatory (Slovenia) during Oct. 26.905-26.909 showing the object at
similar brightness.
      Following a request by E. O. Waagen to AAVSO members, several
observers have sent their confirming observations.  R. Miles, Stourton
Caundle, Dorset, England, reports the following position end figures
for the variable star (at V = 15.2-15.3) from unfiltered CCD images
taken on Oct. 26.963 with a 0.28-m f/10 Schmidt-Cassegrain reflector:
12s.24 +/- 0s.01, 17".6 +/- 0".1.  D. Boyd, West Challow, U.K.,
reports that his V-band CCD exposures with a 0.35-m Schmidt-Cassegrain
reflector, presumably taken around Oct. 27.0 UT, yield V = 15.2, V-I
about 0, and position end figures 12s.26 +/- 0s.19, 17".5 +/- 0".1; he
adds that 4 hr of V- and I-band photometry shows a strong superhump
signal with peak-to-peak amplitude 0.2 mag, indicating that it is
probably a SU UMa-type cataclysmic variable.  The mean superhump period
over this 4-hr interval was 0.0541 +/- 0.0027 days.  R. Stanton, Three
Rivers, CA, reports unfiltered CCD mag approximately 15.4 on Oct. 27.25.
