"Get ready for a stunning display: Geomagnetic storm watch predicts dazzling auroras from Seattle to Boston"

A geomagnetic storm watch has been issued for Tuesday, indicating the potential for aurora lights to be visible from Seattle to Boston. The storm is a result of a coronal mass ejection observed on September 14, with the Earth-directed component expected to arrive early on Tuesday. The University of Alaska Fairbanks Geophysical Institute predicts highly active auroral displays overhead in Alaska and Canada, with auroras likely to be visible low on the horizon for cities such as Seattle, Great Falls, Des Moines, Minneapolis, Chicago, and Boston. The best viewing time is between 10 p.m. and 2 a.m., and a recent new Moon increases the chances of seeing the lights.
