We present new insights into pre-flare and Coronal Mass Ejection behaviour and the evolution of the Active Regions (ARs) by analysing the SOHO/MDI-Debrecen Data (SDD) and the SDO/HMI - Debrecen Data (HMIDD) sunspot catalogues. Our method employs the weighted horizontal gradient of magnetic field (WG_M) defined between opposite polarity spot-groups at the polarity inversion line of ARs. This parameter give the important diagnostic information (i) about the accurate prediction of onset time, (ii) on the flare intensity and (iii) towards CME risk assessment from C class to the X class flare. We discuss additional two auxiliary parameters that guide us which AR be given attention for pre-flare and CME monitoring and further analysis.
