Aurora could light up the sky during the Aug. 27–28 lunar eclipse across North America

A rare red aurora may accompany tomorrow night’s blood-red partial lunar eclipse as NOAA forecasts moderate geomagnetic storms (G1–G2) from 5 p.m. to 11 p.m. EDT, potentially making the northern lights visible from parts of the northern U.S. and Canada, with Canada and Alaska offering the best odds. The coppery-red moon will also be visible in dark skies, though sky-overlap between the two phenomena is unlikely; high-altitude red auroras are possible during stronger solar wind. This follows a recent M-class solar flare and coronal mass ejection. The eclipse begins around 9:23 p.m. EDT, peaks near midnight, and ends around 3 a.m. EDT, providing observers with a rare celestial double feature.
