The reported observations of emission features at 12.33 and 12.22 micrometers in the solar spectrum are discussed. It is concluded that these features are really part of the solar spectrum. The source could be atmospheric or solar. The lines are not observed when the instrument looks several degrees away from the sun. It is probable that these features are of solar origin, but the possibility of atmospheric features is not excluded. If solar, these emission lines are expected to originate from the chromosphere or corona. Balloon-borne solar spectra have been recently obtained with the same interferometer used to record the South Pole data. Examination of the obtained data show a similar emission feature near 1356 per cm.
