In this review, I am going to present the multi-wavelength analysis of C6.1/SF are occurred on
June 12, 2010 from active region NOAA AR 1081 with the complexity of βγ and was associated
with Type II radio burst and Coronal Mass Ejection (CME). We have used ARIES Hα data, SDO-
AIA/HMI, SoHO-LASCO and STEREO/SECHHI data for this study. The are is accompanied
by surge like ejection and later produce Type II radio burst with a slow CME( 382 Kms/sec) and
initially CME speed was high ( 700 Kms/sec). Here we report the co-spatial evolution of the Doppler
enhancements and the chromospheric Hα ribbons observed during X1.2 Class are observed on May
15, 2013. The velocity enhancements exactly match the Hα brightness enhancements with the delay
of approximate 2 minutes delay.
