R1 (Minor) Radio Blackout Impacts
close
HF Radio: Weak or minor degradation of HF radio communication on
sunlit side, occasional loss of radio contact.
Navigation: Low-frequency navigation signals degraded for brief
intervals.

The return of the X-flares

R3 Event 11 Feb, 2023
The return of the X-flares
published: Monday, February 13, 2023 17:05 UTC

Active Region 3217 produced an R3 radio blackout

(i.e. X1.1 flare) which peaked at 1548 UTC or 10:48am EST.

More flares are expected from this region as it moves across the sun
creating occasional degradation of high frequency (3-30 MHz)
communication.
