NOAA’s GOES-19 satellite measurements show the ongoing solar radiation storm has intensified to Severe (S4) on the NOAA Space Weather Scales, and it is still increasing.
Potential Impacts:
Increased radiation exposure risk for astronauts and flights on polar routes.
Enhanced risk to satellites, especially those in geostationary orbit, and space launch systems.
Loss of over-the-horizon high-frequency communications in polar regions.
