NASA, NOAA Track July 2 G2-G3 Solar Storm After Sunspot 4479 Blackout

Summary
A full-halo coronal mass ejection from sunspot 4479 is heading toward Earth and could trigger a G2 to G3 geomagnetic storm on July 2, with NASA and NOAA differing on whether it arrives early or late that day.
The CME followed a June 30 solar flare that ionized Earth’s upper atmosphere and briefly knocked out HF radio links below 25 MHz across parts of North America and the Pacific.
That storm level can disrupt satellites, GPS, radio communications and power transmission, while airlines on polar routes may face temporary communication problems.
Solar Cycle 25 is near its peak, driving a rise in sunspots, flares and CMEs that has made space-weather alerts more frequent; agencies plan to monitor the cloud over the next 48 hours.
