A very high cadence (~1 second) flare program was observing AR 13053 which was approaching the west limb. Interestingly, a long filament (appearing as the dark features in the video) near the solar disk center erupted towards the west and went into the view of IRIS. Such high-cadence observation might provide us an opportunity to understand some physical properties of this erupting filament.
