NEW VARIABLE STAR IN PISCES
     U. Munari, Istituto Nazionale di Astrofisica, Padova Astronomical
Observatory; and P. Valisa, M. Marinelli, and S. Dallaporta, "Asiago Novae and
Symbiotic Stars" (ANS) collaboration, have observed the new variable star
announced on CBET 2616.  CCD photometry provides V = 13.83, B-V = +0.01, V-Ic
= +0.11 for Jan. 1.71 UT.  Absolute optical spectrophotometry (range 400-710
nm; dispersion 0.21 nm/pixel) was obtained with the 0.60-m telescope of the
Schiaparelli Observatory in Varese on Jan. 1.74 UT.  The spectrum is dominated
by a featureless hot continuum with no line visible in emission, and H_beta,
H_gamma, and H_delta in absorption with equivalent widths of 0.77, 0.52, and
0.38 nm, respectively.  No obvious line is visible at the H_alpha wavelength,
suggesting that an emission core could be filling in the expected absorption
line.  The Balmer lines are wide (the FWHM of H_beta is 4.3 nm) and are red-
shifted by +120 km/s, excluding that the variable could be a classical nova
observed close to maximum light.  The object has the appearance expected from
a cataclysmic variable in outburst.

     B. Skiff, Lowell Observatory, notes that this object shows up also in
the Sloan DR7 catalogue as an ultraviolet-bright object (Sloan mag about 21
in all five passbands on 2005 Sept. 13 UT), at the following position:  R.A.
= 23h04m25s.88, Decl. = +6d25'45".7 (equinox 2000.0; formal uncertainty 0".11).
