Abstract : In order to participate in a coordinated satellite and ground-based observation program, the Geophysical Institute of the University of Alaska equipped optical and radio ground stations along a geomagnetic meridian in the northern auroral zone. The polar orbiting satellite, instrumented with a multitude of electron and proton particle detectors was in orbit for three days from November 9 to 11 U.T. 1965. The satellite had an inclination of 94 degrees with an initial apogee of 300 km and perigee of 160 km. The satellite was earth-oriented and was held to about 1 degree attitude during its life. The period during which the satellite was in orbit was magnetically very quiet. Usable coordinated data were obtained during the first day. After that, the auroras observed from the only clear station (College) were too far north to be quantitatively useful. A detailed analysis of the data obtained on the first day has provided basic data on the auroral hydrogen arc. (Author)
