2017 Radio Blackouts

Monday 3 April
R2


A moderate radio blackout happened today; an M5 flare erupted at 9:29am CDT. The possibility of more M-class flares is shrinking as AR2644 turns away from the Earth. I will monitor the alerts from NOAA daily through Friday.

A strong radio blackout happened today; an X2.2 flare erupted at 5:10am CDT, followed by an X9.3 flare at 7:02am CDT. This is quite impressive as the Sun has been heading toward "minimum" for some time.

Active Region 2673 (no longer visible on the Earth-facing side of the Sun) produced an X8.2-rated flare at 11:06am CDT yesterday morning. Wow! This sure is an exciting "heading towards minimum"!
