U. Munari, Istituto Nazionale di Astrofisica, Padova Astronomical Observatory; and P. Valisa and S. Dallaporta, "Asiago Novae and Symbiotic Stars" (ANS) collaboration, have observed the new variable star discovered by K. Itagaki and announced on CBET 2426. A low-resolution, absolutely calibrated spectrum (range 480-880 nm; 0.42 nm/pixel) was recorded on Aug. 26.825 UT with the 0.6-m telescope of the Schiaparelli Observatory in Varese, equipped with a multi-mode grating spectrograph. The noisy spectrum displays a very red, featureless continuum with absorptions visible for H_beta, Mg I (517.4 nm), and Na I (518.9, 519.5 nm), as well as emission from H_alpha and the Ca II triplet in the far red (849.8, 854.2, 866.2 nm). The H_alpha emission line displays a narrow P-Cyg profile. The emission component has an integrated flux of 1.6 x 10**(-13) erg cm**(-2) s**(-1), a full-width-at- half-maximum (FWHM) of 350 km/s, and an heliocentric radial velocity of +60 km/s. The absorption component has an equivalent width of 0.5 nm and an heliocentric radial velocity of -160 km/s. The overall spectral appearance is compatible with a classification as an FU Orionis-type star. CCD photometry, properly corrected for color equations, provides the following magnitudes for the new variable on Aug. 26.83: B = 16.93, V = 14.91, R_c = 13.57, I_c = 12.31.
