| Abstract: | Wind velocities at 140–200 km altitude were observed by a Low-G Accelerometer Calibration System (LOGACS) flown on an Agena satellite during a geomagnetic storm. An interesting wind reversal observed by the satellite at auroral latitudes is satisfactorily explained by the neutral air motion caused by the drift deduced from the ground-based geomagnetic data recorded at stations near the meridian of the satellite orbit. |
