Abstract :
[en] On Dec. 6, 1974, a Black Brant VD rocket was launched from Cape Parry, N.W.T., into the dayside magnetospheric cleft. The prime launch criterion was the detection of 6300-A emission by two ground-based scanning photometers, but support was provided by two ionosondes. The payload passed through a narrow region of soft electron precipitation, a broader region of enhanced electron densities, and a similarly broad region of O I 5577-A and 6300-A emission. At apogee (236 km), the payload had not penetrated into the 5200-A emission, which had a very sharp equatorward boundary and extended far into the polar cap, presumably as a result of antisunward convection.
