V496 SCUTI
     Ashish Raj, N. M. Ashok, and D. P. K. Banerjee, Physical Research
Laboratory, report near-infrared J-, H-, and K-band spectroscopy of the nova
V496 Sct (cf. IAUCs 9093, 9097) obtained with the Mt. Abu 1.2-m telescope (+
PRLNear-Infrared NICMOS3 Imager/Spectrometer).  The interesting aspect of
this nova is the detection of first overtone of carbon monoxide in emission
reported by Rudy et al. on IAUC 9099.  The preliminary reduction of these
Mt. Abu observations, spanning the period Dec. 3.55-8.55 UT, clearly shows
that the emission phase of carbon monoxide is still persisting.  In addition,
the carbon lines are also very strong (cf. IAUC 9099).
     Additional visual magnitude estimates (cf. IAUC 9097):  Nov. 28.705 UT,
7.6 (W. Vollmann, Vienna, Austria); 2.690, 7.5 (M. Lehky, Hradec Kralove,
Czech Republic); 2.690, 7.8 (Vollmann); 3.677, 7.9 (Lehky).
