Rudy, Lynch, Russell, and Woodward also report 0.8- to 5.4- micron spectroscopy of RS Oph on May 1 UT using SpeX on the IRTF. The infrared spectrum of RS Oph is a peculiar blend of very low and very-high-excitation emission lines. Features of N I, O I, and Fe II exist together with some of the highest excitation coronal features seen in the infrared spectra of novae. Coronal lines of [Fe XIII], [Si VI], [Si VII], [Si X], [S VIII], [S IX], and [S XI] are present in the near-infrared; [Mg VIII] and [Si IX] are prominent in the mid-wavelength infrared. The hydrogen line spectrum is very rich, displaying many features from the Pashcen, Brackett, Pfund, and Humphreys series. There is no evidence of thermal emission from dust.
