R3 (Strong) Radio Blackouts from Region 2192

R3 (Strong) Radio Blackouts from Region 2192
published: Monday, October 27, 2014 15:07 UTC

Region 2192 produced an X1 (R3 - Strong) flare at 10:28 EDT (1428 UTC) on October 22nd. Further analysis will be conducted to determine if there is a CME associated with this event as imagery comes in. This region has produced 7 M-class (R1/R2 - Minor/Moderate) flares in the past 48 hours as well as an X1 flare on October 19th. So far none of the CMEs associated with these events are expected to be geoeffective, however, forecasters will keep an eye out for both CME activity and solar radiation storm possibility as the region approaches center disk. Stay tuned for updates.
