The sun has erupted with a series of powerful solar flares over the past 24 hours, including an X8.3-class flare — the most intense solar event recorded in 2026 so far. This extraordinary burst of energy originated from a rapidly expanding sunspot, called Active Region 4366, which has transformed into a solar flare powerhouse since first emerging just days ago. It could mean northern lights on Thursday.
The U.S. National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Prediction Center confirmed that the X8.3 solar flare peaked at 6:57 p.m. EST on Feb. 1 (2357 UTC), releasing a wave of extreme ultraviolet and X-ray radiation that immediately impacted Earth’s upper atmosphere. It came just hours after an X1.0 solar flare (13:28 UTC) and was followed on Feb. 2 by an X2.8 (00:36 UTC) and an X.1.6 (08:14 UTC).
