X-Flare and CME!
AR 4405 erupted this morning at 03:18 UTC (Mar 30) with a surprise X1.5 solar flare. This event launched a halo coronal mass ejection (CME) into space which also appears to have an Earth directed component. Although the main bulk of plasma is heading to the east, the edge of the CME should pass Earth within the next 48 hours. A moderate (G2) geomagnetic storm watch has already been issued for March 31st. Stay tuned!
ALERT: Type II Radio Emission
Begin Time: 2026 Mar 30 0300 UTC
Estimated Velocity: 1872 km/s

Today’s X1.5 solar flare launched a coronal mass ejection into space with a likely earth-directed component. An arrival is possible late (evening UTC+0) on Tuesday, 31 March. Expect increased geomagnetic conditions following the impact possibly up to the G2 moderate storm level.

Surprise! An X1.5 solar flare (R3-strong) peaked today at 03:19 UTC. Soruce of the solar eruption was Active Region 4405 (Beta-Gamma) in the Sun’s southeast quadrant.

A Coronal Mass Ejection (CME) was launched during this solar flare with the bulk of the ejection heading south-east of us as we can see on this animation from SOHO/LASCO below. We do however see a clear asymmetrical full halo outline which gives us a high confidence that we should see at least a glancing blow from this event at our planet, likely late (UTC evening) tomorrow, Tuesday 31 March.
