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.
