The largest sunspot region of Solar Cycle 24 - Region 2192 ('beta-gamma-delta') unleashed its fourth X-class solar flare since it rotated onto the Earth side of the Sun on October 25, 2014. The event lasted more than 1 hour. It started at 16:55, peaked at 17:08 as X1.0 and ended at 18:11 UTC.
Although this region is continuously producing strong and major flares it still didn't deliver a significant Coronal Mass Ejection (CME). Analysis of the latest event is still in progress but it too appears without a significant CME.
Radio Blackout threshold reached R3 (Strong) level that can cause wide area blackout of HF radio communication, loss of radio contact for about an hour on sunlit side of Earth and low-frequency navigation signals degraded for about an hour. The main communications impacts from this event are over the Pacific Ocean...
