OSTI ID:6065164
A bright OH Meinel airglow structure event was recorded on June 15, 1983 from Sacramento Peak, New Mexico. The MAPSTAR interferometer was operated in conjunction with low-light-level infrared imaging isocon camera system provided by the University of Southampton, England. The camera was co-aligned with the meter. The structures were measured at elevation angles near the horizon. Apparent wavelength, periods and phase velocities of 24 + or - 1 minutes, and 28 + or - 2 meters/second respectively, were calculated for the recorded structure. The interferometer data show intensity modulations of 20-40% within the structure. A mean rotational temperature of 165 /sup 0/K was calculated using the interferometer spectral data and temperature modulations of 5 to 10 /sup 0/K were recorded in phase with the intensity modulations. This report discusses the structure and performance of the MAPSTAR interferometer and telescope, as well as the results obtained using the sensor. Data collected shed new light on the phenomena under investigation and will provide a foundation for studies in the future.
