coondoggie writes "The National Oceanic and Atmospheric Administration's Space Weather Prediction Center today issued a geomagnetic storm bulletin for the next 12 hours. Such storms can cause problems with Global Positioning Systems and power grids.
NOAA stated: "Great anticipation for the first of what may be three convergent shocks to slam the geomagnetic field in the next twelve hours, +/-. The CME with the Radio Blackout earlier today is by far the fastest, and may catch its forerunners in the early hours of August 5 (UTC) — at earth. Two impacts are expected; G2 (Moderate) to G3 (Strong) Geomagnetic Storming on August 5, and potentially elevated protons to the S2 (Moderate) Solar Radiation Storm condition, those piling up ahead of the shock."
