Scientific paper

A rocket (ADD-II-128) launched into bright aurora at Churchill, Canada on February 21, 1974 provided in situ measurements of electron influx and resulting 5577 A emission intensity. The rocket descended through a broad and fairly homogeneous arc of 70 kR intensity. Measurements of downward electron energy flux (18 keV-20 eV) at the rocket during the time it descended from 120 to 110 km were compared with resulting emission intensities directly below the rocket. They yielded excitation efficiencies of 0.67 kR of 5577A O I and 180 R of 4278A N2(+) per erg/sq cm sec energy influx. These values agree well with calculated values for bright auroras.
