Geomagnetic storm reached G2 levels, amazing auroras photographed from ISS
A Coronal Mass Ejection (CME) unleashed by solar filament eruption on August 15 started interacting with Earth's magnetic field around 07:00 UTC on August 19 causing, at first, only a minor instability.As the Earth passed through the plasma cloud the effects increased and reached G2 – Moderate level threshold (Kp=6) at 23:01 UTC.At these levels area of impact is primarily poleward of 55 degrees Geomagnetic Latitude. Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms. Satellite orientation irregularities may occur; increased drag on low Earth-orbit satellites is possible. HF (high frequency) radio propagation can fade at higher latitudes. Aurora may be seen as low as New York to Wisconsin to Washington state.Geomagnetic … Read more »
