We report the first results from the study of prominence eruption on 2014 Nov 01 followed by
two-ribbon solar flare. The ejection triggered a coronal mass ejection (CME) that was well
observed in the LASCO C2 field of view. We used multi-channel observations from AIA/SDO,
SWAP/PROBA2 and SoHO/LASCO to study the morphology and kinematics of the prominence
eruption. Evolution of two-ribbon flares is morphologically characterized by separation of the two
ribbons in the chromosphere. Such separating motion is believed to provide a signature of the
reconnection process occurring progressively higher up in the corona. Ribbon's behaviors such
as a separation velocity and an intensity evolution in the EUV lines with different temperature
formation are analyzed. The trigger mechanism of the eruption process is discussed.
