A pre-eruption disturbance of an active filament has been observed. The disturbance is characterized by untwisting rotation and vigorous upward motion. It starts at the site where microflares took place, and appears in the late phase of magnetic flux cancellation beneath the central part of the filament, when more than 1020 Mx flux had disappeared.
