Between the X-class flare and a slow solar storm hit, there's a lot of radio signal degradation today. On Earth's dayside, we have an R3-level radio blackout impacting HF and VHF bands (see the "bull's-eye" color pattern on the map). Higher frequencies like GPS/GNSS are being affected by an increase in turbulent zones shown by ROTI (blue-purple patches). Stay vigilant radio operators!
30 Jun 2026- Space Weather Update! What happened today and what might that mean as we approach July 4th weekend? Check out this SWPC video to learn about the recent solar flare, CME, and what our forecasters will analyze through the overnight and adjust the forecast as needed.
Our Sun does more than sizzle: Region 4479 just fired an X1.1-flare and big solar storm while in the Earth-Strike Zone! Fast wind from a coronal hole south of the source region could deflect the structure northward, but we could catch some of it. Waiting for coronagraphs to inform model runs now.
An X1.1 flare (R3-Strong) occurred at approx 30/2050 UTC from Region 4479 in the north center disk. Analysis will be conducted when imagery becomes available to determine if an Earth-directed CME was associated with this event.
