FLITECAM observed the H + K-band spectrum on Feb. 19, 2014 and Feb. 27, 2014 with strong emission features at 1.55-1.65 μm and 1.77 μm. The detail of the geometry of the 1.77 μm emission peak has enabled it to be identified as permitted lines of Co ΙΙ rather than a blend of Fe group lines and Co ΙΙ as previously believed. The strongest emission lines of Co ΙΙ and [Co ΙΙΙ] are presented in the bottom of each plot, and triangles indicate the locations of lines predicted to be strong in the model for comparison.
Favorable atmospheric transmission achievable in the stratosphere onboard SOFIA has enabled FLITECAM spectra to be the only data collected on SN 2014J that spans the entire feature profile.
