A long duration M-class solar flare measuring M1.6 at its peak time erupted on October 18, 2014. The source was large Active Region 2192 which just emerged from the southeast limb. The event started at 07:02, peaked at 07:58 and ended at 08:49 UTC.
This region already had several significant eruptions and sent a massive CME into the space as it was transiting onto the Earth side. A sharp uptick in solar activity is very likely over the coming days.
The region is still not in geoeffective position but is capable of producing strong eruptions.
NOAA SWPC forecasters estimate 30% chance for M-class, and 5% chance for X-class solar flare over the next three days (October 18 - 20)...
