A sky-mapping filter photometer was used to measure the 630.0 nm airglow enhancement produced by the explosive release of 3 x 10 to the 26th CO2 molecules. The morphology of the enhanced airglow region was traced in a series of 630.0 nm intensity contour maps as a function of time. It is shown that the enhancement reached a central brightness peak of approximately 400 R about 2 minutes after the explosion, and a diameter of about 250 km some 3 minutes after release. The measurements of central intensity and enhanced region radius as a function of time are compared with theoretical estimates of Mendillo and Herniter (1984) of diffusive expansion of CO2 molecules from either a point release or from an initial, extended volume. It is found that while the peak intensities in both the theoretical estimates and the observational data were in agreement, the measured decay of the 630.0 nm intensity and the growth in size of the enhanced region are different from the model predictions. The measured 200 m/s drift southeastward of the enhanced region is found to be consistent with the motion of the central thermosphere as described by optical Doppler shift measurements.
