At Providence, solar aurora may be visible overnight Mon into Tue and, to a lesser extent, Tue into Wed. Aurora is unusual at latitudes this far south, but it typically happens a few times every year.
Weather at Providence during the potential aurora will be partly cloudy increasing from 25% cloud cover Mon sunset to 5% overcast Tue sunrise, temperature low 9°F and near-zero chance of rain; then mostly cloudy from 66% cloud cover Tue sunset to 90% overcast Wed early morning, temperature about 30°F and 40% chance of rain.
Geomagnetic storms are usually imperceptible to humans, but, in addition to visible aurora, they may cause disruptions of radio communications and systems that rely on orbiting satellites, such as Global Positioning System (GPS), and in rare cases can affect the electrical power grid.
The atmosphere usually shields earth from harmful biological effects. Travelers in high-altitude aircraft may be exposed to slightly higher than normal radiation.
