Emissions from excited hydroxyl molecules constitute a significant portion of the near infrared airglow from the night sky. Extensive measurements of the characteristics of these emissions have been made by Utah State University and the Air Force Geophysics Laboratory from an AFGL KC-135 aircraft and from the ground. Observed variations in emission intensities are summarized in this report. The specific types of behavior include diurnal variations day-to-day variations spatial variations associated with auroras and spatial variations associated with the patchiness of hydroxyl emissions. Some of the variations repeat very regularly while others are more erratic. The presented data are a significant input to infrared phenomenology.
