3.5mm Depression features associated with Hα `disparitions brusques'
Abstract
The characteristics of 3.5 mm depression features associated with two `disparition brusques' observed in Hα are discussed. The millimeter depressions still exist, although reduced in strength, after the disappearance of the Hα filament. The two depressions correspond to temperatures of 600 and 450 K before and to 200 and 250 K after the Hα filament disappearance.
