A rocket-ground study of electron precipitation in the cleft region
Abstract
Electron spectra obtained from a Black Brant rocket launched at Cape Parry on December 6, 1974 and traveling across the cleft have been interpreted in correlation with 5577/6300 A data obtained from a photometer scanning through the meridian along the rocket flight path with one complete scan each 7.5 seconds. One inverted V structure recorded by the rocket spectrometer over a 10 km path is identified by the optical data to be of only 15 sec duration. Other smaller V events are identified, similarly of short duration and possibly with poleward motion. The value of remote measurements of cleft dynamics and their role in furthering understanding of this region is illustrated.
