We present here the evolution of a quiescent filament during 26 August to 29 September, 2013. For the evolution of filament we have used the data from Solar Dynamics Observatory (SDO), STEREO and GONG H-alpha. After the survival of nearly one month, it was erupted on 29 September, 2013 around 21:15 . The eruption was associated with GOES C 1.6 flare, Coronal Mass Ejection (CME), and type II radio bursts. The Kinematics of filament eruption and CME is also discussed here. In order to discuss the magnetic causes of filament eruption, we have used the magnetic field data from HMI onboard SDO satellite. We have observed the magnetic flux cancellation at filamentís footpoints, which could be possible reason for its eruption. Finally, we have interpretated our observations in light of eruption models.
