In this paper , we present a study of an M2.2 class solar flare of 26 November 2000 from NOAA AR 9236 .
The flare was well observed by various ground based observatories ( ARIES , Learmonths Solar Observatory ) and space borne instruments ( SOHO , HXRS , GOES ) in time interval between 02:30 UT to 04:00 UT .
The flare started with long arc-shape outer flare ribbon .
Afterwards the main flare starts with two main ribbons .
Initially the outer ribbons start to expand with an average speed ( \sim 20 km s ^ { -1 } ) and later it shows contraction .
The flare was associated with partial halo coronal mass ejection ( CMEs ) which has average speed of 495 km s ^ { -1 } .
The SOHO/MDI observations show that the active region was in quadrupolar magnetic configuration .
The flux cancellation was observed before the flare onset close to flare site .
Our analysis indicate the flare was initiated by the magnetic breakout mechanism .
