NOAA forecasters say there is an 85% chance of geomagnetic storms on Oct. 30th when a CME (described below) is expected to hit Earth’s magnetic field. It could be a strong storm, category G3, which means auroras could descend to mid-latitudes–places like Kansas, Nebraska, Oregon, Virginia. The CME’s arrival time is uncertain; estimates range from midday on Oct. 30th to the early hours of Oct. 31st.
