λ 4097.3 N iii emission in the chromospheric spectrum?
Abstract
The recent tentative identification of a chromospheric emission line at λ⊙ = 4097.342 Å with the NIII transition 3s2S1/2 $#x2212; 3p2P∘3/2 is discussed. It is shown that the observed intensity is inconsistent with the observed flux in the XUV resonance lines and considerably greater than the predicted intensity from the chromosphere-corona transition zone. Microphotometry of a plate shows that the `line' is a short interval of continuum between absorption lines.
