	abstract = {We carried out spectroscopic observations of the optical transient near M31 reported in ATel $\#$611 (RA = 00h38m54.63s DEC =+40o27{\textquoteright}34.2" (J2000)) from the 1.3m telescope of the Skinakas Observatory in Crete (Greece) on the nights 28 and 29 September 2005. The spectra covered the range 3800-7000 angstroms. All the lines of the Balmer series up to H-8 appeared strongly in emission. The equivalent widths of the H-alpha and H-beta lines (the strongest emission features) on 28 September 2005 were -550+-25 angstrom and -220+-20 angstrom, respectively and the FWHM 1800+-30 km/s in both lines.},
