Abstract
Filtergrams and spectra of a disparition brusque are discussed. The total mass of the prominence prior to eruption is estimated to be ∼-2×1015g. A prominence had erupted 41/2 days earlier from the same active region. The eruptive prominence which we observed formed some 11 0000 km above the photosphere. In the later phase of the eruption the outward acceleration approached the acceleration due to gravity at the same height. Down falling material along vertical structures was observed with velocities exceeding 100 km s−1. The vertical structures became twisted during the eruption indicating a field aligned current of approximately 1010 amps.
