An Astrobee D rocket carrying a dual-channel radiometer (1.40- to .1.65-gm and 1.85- to 2.12-gm spectral band passes) was launched on March 6, 1972, at 0200 LT from Poker Flat, Alaska.T he spectrabl and passews ere chosens o that the lower (v -- 2, 3, 4, 5) and upper (v -- 7, 8, 9) vibrational levels of OH in the .Av -- 2 sequence could be monitored simultaneously. Launch criteria were established from groundsbased radiometric observations that indicated a steady.night airglow of 240 kR• in the 1.40- to 1.65-gm band pass 2 hours prior to and throughou•tt he flight.
