V1280 Scorpii.

Abstract (from CDS):

M. Sitko, Space Science Institute; and R. Russell, D. Lynch, and R. Rudy, The Aerospace Corporation, report 0.8- to 5.5-micron spectroscopy of V1280 Sco on May 20.5 UT using the SpeX instrument of the IRTF. The excitation of the emission-line spectrum remains very low, with features of neutral carbon weak but still detectable. N I is also present, along with very strong lines of Fe II. O I features are also prominent, with continuum fluorescence now rivaling fluorescence by Lyman-beta as the dominant excitation mechanism. The reddening deduced from the O I lines is E(B-V) = 0.95. There is a weak P-Cyg absorption on the He I singlet at 2.058 microns. The unidentified infrared emission features at 3.3 and 3.4 microns reported above by Russell et al. are also seen.
