Observations of the geocoronal Lyman beta emission rate were made with an electrographic camera/spectrograph during the Apollo 16 mission. These data along with geocoronal Balmer alpha airglow measurements obtained simultaneously from the D2A spacecraft are found to agree, to within experimental error, with an optically thick geocoronal hydrogen model.
