Sunspot region 2403 remains active and this morning it produced the strongest solar flare thus far: an impulsive M5.6 (R2-moderate) solar flare that peaked at 07:33 UTC. No radio sweeps were reported from this impulsive solar flare which indicated that a coronal mass ejection from this event would be unlikely. SOHO coronagraph imagery confirms that this solar flare indeed did not launch a coronal mass ejection.
