Update: R1 and R2 radio blackouts

Update: R1 and R2 radio blackouts
published: Monday, October 06, 2014 13:19 UTC

Regions 2172 and 2173 produced R1 (Minor) and R2 (Moderate) solar flare radio blackouts yesterday at 02/1744 UTC (1344 EDT) and 02/1901 UTC (1501 EDT) respectively. Analysis of SOHO/LASCO coronograph imagery confirms that the associated CME is not Earth-directed and no geomagnetic impacts are expected as a result of this event.

Stay tuned here for updates.
