This chart tracks in real time the solar X-ray flux recorded by NOAA GOES satellites in geostationary orbit.
Intense solar flares (M and X classes) ionize the ionosphere's D layer, causing Sudden Ionospheric Disturbances ($SID$) or total blackouts across the entire 27.000 to 27.995 MHz spectrum.
Automatic update every 3 minutes (SWPC API).
This specialized panel displays the band opening status across the complete 27.000 to 27.995 MHz spectrum, broken down by continents and global geographical zones.
Allows instant evaluation of the most favorable propagation paths:
