A moderately strong and impulsive solar flare measuring M4.0 at its peak time erupted from huge central region on the Sun on October 24, 2014 at 07:48 UTC. The event started at 07:37 and ended at 07:52 UTC.
A Type II (664 km/s) and IV radio emission were associated with the event. Type IV emissions occur in association with major eruptions on the Sun and are typically associated with strong Coronal Mass Ejections and solar radiation storms.
The source of today's M4.0 flare Region 2192 located almost at the center of the disk. This region has 'beta-gamma-delta' magnetic configuration and is capable of producing more strong to major eruptions on the Sun. Earth directed CMEs from this region are now highly likely.
Region 2192 is the largest sunspot of this cycle and this is how the it looked like on October 23 during partial solar eclipse:
