Proper motion of sunspot is the motion of spot that still happen within correction from the motion of Solar differential rotation. Some of motion could be the source for generation of energy, a mechanism to form Solar flare and other activity. Some researcher guess that the proper motion of sunspots may cause the dynamical activity in upper atmospher, such as Solar flares in corona. Generally, there is classification for Solar flares depend on its amount of energy. So, AR12192 from October 24th, 2014 choosed for this research. On that day, there is major Solar flare and classified as X3.1-class Solar flare. To know how the connection between sunspot proper motion and Solar flare, 32 sunspots in that active region have been measured for each velocity from images took by SDO/HMI instrument in continuum and magnetogram. Also the velocity for sunspots with different magnetic polarity and its significant alteration in motion.
