Overview

• Confirmed sightings overnight included north-east Scotland, northern England and the Midlands, with photos reported as far south as West Cork in Ireland and isolated views in southern England.
• NOAA and the UK Met Office reported the late‑August eruptions have produced G2 to G3 geomagnetic conditions with brief potential for G4, following the CME arrival late Monday into early Tuesday.
• NOAA’s forecast map showed the aurora’s southern viewing line reaching roughly 16 to 18 U.S. states across the northern tier and parts of the Midwest, including Illinois, Michigan and Oregon.
• Forecasters described two Earth‑directed CMEs with the faster eruption overtaking the first in a “cannibal” configuration, a setup that can yield stronger and more variable responses.
• Visibility remains highly dependent on local cloud cover and a bright waxing gibbous Moon, with clearer skies favored at times in northern UK regions and parts of New England, the Great Lakes and Montana.
