RS OPHIUCHI
     R. K. Das, N. M. Ashok, and D. P. K. Banerjee, Physical
Research Laboratory, report near-infrared JHK spectroscopy of RS
Oph (cf. IAUC 8673) obtained with the Mt. Abu 1.2-m telescope (+
PRL Near Infrared NICMOS3 Imager/Spectrometer) on 2006 Oct. 13.58
UT (243 days after the outburst).  The signature of the secondary
red giant is now seen through the presence of the CO first-overtone
bands in the K band.  The other prominent lines, seen in emission,
are H I lines of Paschen_beta, Paschen_gamma, and Brackett_gamma
and He I lines at 1.0830 and 2.0581 microns.
