Sun Unleashes X8.3 Flare: Strongest of 2026!
3 Feb
Summary
- An X8.3 solar flare, the strongest in 2026, erupted from region 4366.
- Radio blackouts occurred in the South Pacific and Australia.
- Potential minor geomagnetic activity and auroras possible around February 5.
As of February 3, 2026, the Sun has experienced significant solar activity, including at least 18 M-class flares and three X-class flares within the past 24 hours. Most notably, an X8.3 flare, the most powerful recorded this year, erupted.
This intense activity originated from sunspot region 4366, which has rapidly expanded and displayed unstable magnetic behavior. The X8.3 flare, peaking on February 1, emitted strong radiation, causing R3-level radio blackouts in the South Pacific.
Consequently, shortwave radio signals were disrupted across eastern Australia and New Zealand. Scientists are closely monitoring for any associated coronal mass ejections, with initial assessments indicating most material may bypass Earth.
However, a slight impact is anticipated around February 5, potentially causing minor geomagnetic disturbances and increasing the likelihood of auroras at higher latitudes. Region 4366 remains active and is turning towards Earth, with further solar events expected.
