M. Sitko, Space Science Institute; D. K. Lynch, R. W. Russell, and R. J. Rudy, The Aerospace Corporation; and C. E. Woodward, University of Minnesota, report 0.8- to 5.5-micron spectroscopy of the nova V2670 Oph (cf. IAUC 88947, 8948, 8949, 8956) on Oct. 4 UT using the Infrared Telescope Facility (+ Spex). The spectrum remains low in excitation, still displaying emission lines of Fe II, N I, and O I. However, the C I lines that were strong in mid-June are barely detectable, and the He I 1.083-micron line is now the strongest feature in the infrared spectrum. The broad components of the emission lines have disappeared entirely. This nova has not formed dust and is unlikely to do so at this late stage.
