Abstract (from CDS):

M. Della Valle, Osservatorio Astrofisico di Arcetri, Florence; D. Hutsemekers, University of Liege; and I. Saviane and E. Wenderoth, European Southern Observatory (ESO), write: "Preliminary analysis of a spectrum (range 380-740 nm; resolution about 0.1 nm) of the variable star reported on IAUC 8184, obtained on Aug. 22.02 UT with the ESO 3.6-m telescope (+ EFOSC2) at La Silla, shows a reddened continuum characterized by a lack of the typical signatures exhibited by Fe- or He/N-type classical novae in their early evolution. We detect faint H_alpha and H_beta emission lines flanked by P-Cyg profiles. The expansion velocity derived from the minima of the P-Cyg profiles is about 500 km/s. All of this suggests this object not to be a classical nova, but possibly a post-asymptotic-giant-branch star in flare-up, a V4332 Sgr-type object (Martini et al. 1999, A.J. 118, 1034), or a V838 Mon-type object (IAUC 7785; Bond et al. 2003, Nature 422, 405) caught at an early stage."
