The glowing cloud near the ram surfaces of the Space Shuttle was observed with a hand‐held, intensified spectrograph operated by the astronauts from the aft‐flight‐deck of the space shuttle. The spectral measurements were made between 400 and 800 nm with a resolution of 3 nm. Analysis of the spectral response of the instrument and the transmission of the shuttle window was performed on orbit using earth‐airglow OH Meinel bands. This analysis resulted in a correction of the shuttle glow intensity in the spectral region between 700 and 800 nm. The data presented in this report is in better agreement with laboratory measurements of the NO 2 continuum.
