X3.9 Solar Flare + CME (5/10/2024) - SolarHam.com
The largest solar flare yet produced by AR 3664 was observed at 06:54 UTC (May 10, 2024). This X3.9 blast is associated with a Type II radio emission with an estimated velocity of 1248 km/s, along with a 10cm radio burst (TenFlare) measuring 900 SFU and lasting 16 minutes. A coronal mass ejection (CME) is now becoming visible and it appears the main bulk is heading to the west, but there will likely still be an Earth directed component.
A reminder that a Severe (G4) geomagnetic storm watch is in effect starting later today thanks to multiple expected incoming CMEs associated with strong solar flares the past few days.
