Abstract The photometer EMO-5 aboard the circular orbit satellite IC-B-1300 delivered intensity data in the equatorial belt of the atomic oxygen emission line at 630 nm during solar maximum conditions. The asymmetry of the equatorial emission arc is explained by a transequatorial neutral wind, the effect of which must be added to that of the vertical E × B plasma drift. No evident connection between geomagnetic activity and brightness could be seen. Highest brightness occurred in the evening, possibly as a consequence of a reversal of the E × B drift. During the September equinox a secondary maximum was observed, south of the main arc.
