Solar Storms at M2.8 Solar Flare
Right now
The most recent data we hold from GOES XRAY arrived 24 hours ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
Reported by GOES XRAY 174 days ago.
What the source measured
GOES XRAY reported: M2.8 solar flare detected by GOES X-ray sensor. Peak flux: 2.79e-5 W/m². Moderate solar flare. Minor HF radio effects on sunlit side of Earth.
How we know
Confirmed by 3 independent sources, including GOES XRAY.
Our own score for this event is 15 out of 100, at 60 % confidence.
The score is ours, computed from intensity, exposed population and local history — not the source’s.
Computed under scoring rules v1. Rows carrying other versions were judged by different rules and are not directly comparable.

| Soho Lasco Note | This CME is visible as a partial halo directed to the northeast in SOHO LASCO C2/C3 and GOES CCOR-1 imagery. This event is not seen in STEREO A COR2 imagery in real-time due to a data gap starting at 2026-03-14T12:09Z. The source is an M2.7 flare and eruption from Active Region 14392 (S15E19) starti |
