Giant sunspot erupts today with 4th substantial flare since Oct 19.
Region 2192 has ‘beta-gamma-delta’ magnetic configuration and is capable of producing more strong to major eruptions on the Sun. Coronagraph data from the Solar and Heliospheric Observatory (SOHO) suggest that the explosion did not hurl a significant CME toward our planet. Interestingly, none of the X-flares from this active region has so far produced a major CME. This active region is directly facing Earth so any produced CME would be geo-effective.
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.
