✦ Synopsis

Wavelengths of clean atmospheric water lines, and some solar lines, in the wavelength interval 10750 A to 10900 A have been measured to an accuracy approaching ~ 1 m/~. Strengths and wavelengths have been measured for all atmospheric water lines with absorption coefficients > 5 • 10 -4 cm -a gm -1 cm -2 at N 280K, that lie within 15/~ of the He I 10830 A feature. Theprofile of the stronger He component is affected by a weak water line which reduces atmospheric transmission by nearly 1% with 10 mm precipitable water in the line of sight.
