Region 2205 Produces a X1 Solar Flare - R3 Radio Blackout Event (Updated)

Region 2205 Produces a X1 Solar Flare - R3 Radio Blackout Event (Updated)
published: Saturday, November 08, 2014 15:15 UTC

Region 2205 produced a X1 solar flare (NOAA Scale R3 - Radio Blackout) event at 1726 UTC (12:26 EST) on 07 November 2014.  The impact of the flare itself was short-lived degradation to HF radio communications on the daylight side of Earth.  There was a coronal mass ejection (CME) associated with this event, and although only a couple of ESA/NASA SOHO LASCO coronograph images are available at this time, it is clear the associated CME is not particularly fast nor headed directly at Earth (shown in this LASCO image as the faint structure propagating to the upper left).  Detailed modeling of this event will occur once all coronagraph images become available to determine what, if any, impact can be expected as a result.
