A NEW CME JUST LEFT THE SUN: Yesterday, July 23rd, an unstable filament of magnetism in the sun’s southern hemisphere exploded. The blast hurled a bright and interestingly textured CME into space: movie. NOAA analysts are studying the CME now to determine if it has an Earth-directed component. Stay tuned.

Potential Impacts: Area of impact primarily poleward of 55 degrees Geomagnetic Latitude.
Induced Currents – Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms.
Spacecraft – Satellite orientation irregularities may occur; increased drag on low Earth-orbit satellites is possible.
Radio – HF (high frequency) radio propagation can fade at higher latitudes.
Aurora – Aurora may be seen as low as New York to Wisconsin to Washington state.
