"textContent": "High-energy solar protons briefly reached S1 - Minor solar radiation storm levels on May 26, 2026, following a large partial halo coronal mass ejection (CME) from the far side of the Sun. The eruption was first detected by the GOES-19 CCOR-1 coronagraph at 22:00 UTC on May 25. Forecast calls for a 10% chance of another S1 or stronger solar radiation storm on May 27.\n\nSource",
