Solar Storms at M2.4 Solar Flare
Reported by GOES XRAY 189 days ago.
What the source measured
GOES XRAY reported: M2.4 solar flare detected by GOES X-ray sensor. Peak flux: 2.36e-5 W/m². Moderate solar flare. Minor HF radio effects on sunlit side of Earth.
How we know
3 recorded sources include GOES XRAY; independence is not established by this count.
Our own score for this event is 22 out of 100.
This is our versioned heuristic index, not source severity or a calibrated probability. Urban PEI does not count unique people.
Computed under scoring rules v1. Rows carrying other versions were judged by different rules and are not directly comparable.

| Soho Lasco Note | CME first seen to the SE by SOHO LASCO C2 beginning at 2026-03-18T10:36Z, as well as by GOES CCOR-1 in later frames. This CME is obscured by bright, partial halo CME: 2026-03-19T09:23Z in STEREO A COR2 and is blocked by the pylon in SOHO LASCO C3. The source of this event is a region of dimming cent |
