M. L. Sitko, University of Cincinnati and Space Science Institute; and D. K. Lynch, R. W. Russell, and C. C. Venturini, Aerospace Corporation, report on 0.8- to 5.5-micron spectroscopy of BF Cyg on Aug. 22.37 UT using SpeX at the Infrared Telescope Facility. The star appears to show a low-excitation shell. Many weak emission lines are present against what appears to be a normal stellar continuum. The H I Paschen lines are very weak in emission, and the Brackett and Pfund lines were undetected except for weak Br_gamma. He I 1.0830-microns showed a P-Cyg profile, but He I 2.0581-microns was not detected. Weak absorption of the first overtone of CO at 2.3 microns was seen, and the Ca II infrared triplet was present in emission. A strong emission line appears near 3.3145 microns. The lines were not resolved spectrally and thus are very narrow.
