Motion features of sunspots in active regions NOAA AR 11158, NOAA AR 11283 and NOAA AR11515

  • Yu.A. Fursyak Crimean Astrophysical Observatory


Using SDO/HMI data we analyze proper motions of sunspots in three active regions of the current solar cycle 24. The character of motions as well as trajectories of sunspots are explored. Also we performed an estimation of sunspot velocities. We studied changes of the character of flare activity in sunspot groups due to the presence of significant proper motions of individual sunspots in an active region. We note the impact of sunspot motions on the formation of flare-active delta configurations in the magnetic field.
