The Evolution of X1.2 Class Flare occured in complex βγδ magnetic configuration region NOAA AR 11748 on May 15, 2013 has been discussed by the Atmospheric Imaging Assembly(AIA) on board the Solar Dynamic Observatory(SDO) to analyse this flare. From the SDO AIA 304 A data, we observe the sets of coronal loops over the active region which shows the upward motion and by analysing the pre-flare data sets; we get the footprints of this X-Class flare. On the active region, the small flare is observed due to which the magnetic field is interrupted and the whole system gets imbalanced so that this flare occured which is associated with Coronal Mass Ejection(CME). We get the evidences of the ribbon seperation from the ARIES Hα and SDO AIA 1600 A data.
