GEOMAGNETIC STORM WATCH: Strong G3-class geomagnetic storms are possible today, May 11th, when a CME is expected to hit Earth's magnetic field. During G3-class storms auroras have been sighted in the USA as far south as Oregon, Nebraska and Virginia. Aurora alerts: SMS Text.

Here is the CME leaving the sun during the late hours of May 9th:

At the time, the CME was traveling faster than 1,000 km/s (2.2 million mph). Shock waves at its leading edge accelerated protons to nearly light speed; they have been peppering our planet's upper atmosphere for the past two days. These are signs of a potent CME, fully capable of causing a geomagnetic storm when it reaches Earth.

According to NOAA's latest forecast model, the impact should occur on May 11th at approximately 1200 UT. A NASA model predicts 1800 UT. The difference gives a sense of the uncertainty in both models. Whenever the CME arrives, subscribers to our Space Weather Alert Service will receive an instant text message announcing it.
