NOAA forecasters estimate a 90% chance of geomagnetic storms on Nov. 2nd-3rd
when a fast-moving stream of solar wind is expected to hit Earth's
magnetic field. Solar wind speeds could exceed 800 km/s and spark a
strong G3-class geomagnetic storm. Sky watchers in the USA should be alert for Northern Lights as far south as, e.g., Oregon and Illinois.
