CME and Particle Storm of November 8, 2000

Ongoing Particle Storm from the Sun

Energetic particles are bombarding the detectors of several instruments on-board SOHO, showing up as "snow" in the images below.

The Earth's environment is currently bombarded by high energy particles accelerated by a powerful solar eruption last night. A strong flare (M8) and coronal mass ejection were observed by the SOHO instruments. The flux of high-energy protons near Earth is now ~100,000 times greater than normal. This is the 4th largest proton event since 1976.

This radiation storm may fade or black out all HF radio communication at high latitudes. Some earth-orbiting satellites are likely to experience electronic glitches. Astronauts on the International Space Station are safe inside the capsules but extravehicular activities will probably not be allowed while the storm is in progress.
