The intensity and latitudinal distribution of the O I 1304- and 1356-¿ nighttime emissions associated with the equatorial anomaly have been observed by the ultraviolet spectrometer on board the Ogo 4 satellite. Conspicuous effects, apparently related to magnetic activity, have been noticed during the geomagnetic storm of October 29 to November 4, 1968. These effects include (1) large latitudinal variations of the 1304/1356-¿ intensity ratio, (2) large interhemispheric asymmetries in the 1356-¿ intensity, and (3) a pronounced longitude dependence in the airglow intensity during the recovery phase. The results of model calculations allowing for changes in the vertical E¿B drift velocity, the meridional and zonal wind velocity, and neutral composition are discussed. The variations of the 1304/1356-¿ ratio can be accounted for by changes in the altitude of the F layer due to neutral wind and E¿B drift. Zonal wind speeds approaching 300 m/s explain the interhemispheric asymmetries observed in the Pacific sector, and both drift velocity and composition changes can explain the longitudinal differences observed during the recovery phase. In addition, it is found that the ratio 1304/1356 ¿=6 maps out Hmax(F2) extremely well, independent of which E¿B drift or neutral wind model is used.
