We obtained an optical spectrum of PT And = M31N 2010-12a (c.f. CBET 2574)
according to the report by maehara-san on 2010 Deceber 10.
No prominent emission lines were detected in our spectra as observed
in ordinary
classical or recurrent novae in its early decline phase.

Our result is in agreement with recent reports that the object appear to be
a dwarf nova  ( [vsnet-alert 12484] , [vsnet-alert 12527]).

Our spectrum on Dec.10 is showed in the following page:
