An unexpected geomagnetic storm has begun earlier than expected, and the US National Oceanic and Atmospheric Administration (NOAA) is warning of new solar flares. The storm, which was recorded overnight, was caused by material from recent solar flares reaching Earth earlier than expected, briefly reaching a strong level.
NOAA has declared a G3-level geomagnetic storm watch as Earth braces for more strikes. The solar storms are still ongoing; the strongest is expected in the near future. The solar flare of November 5, according to NOAA, will reach Earth on the evening of November 6 or the morning of November 7.
The storms can cause satellite navigation failures, interruptions in high-frequency radio communications, and voltage fluctuations in power systems, especially at high latitudes. During intense magnetic storms, auroras can be observed further south, reaching mid-latitudes.
