🌞 Solar Activity Solar flare activity level: R0 – Eruptive Flare (No Radio Blackout) Details: Solar flare activity was observed over the past 24 hours, with the strongest flare reaching C1.9 from Active Region (AR) 4551, located at S12E52. Event time: 11 October 2026 at 02:53 UTC, or 09:53 on 11 October 2026 (Thailand time). Outlook: Low-level C-class flares may occur tomorrow, particularly from Active Region (AR) 4551. 🌍 Geomagnetic Field Geomagnetic storm level: G0 – No Geomagnetic Storm Current conditions: Solar wind speed and particle density have decreased. Currently expected to remain at a low level. Outlook: Geomagnetic activity is forecast to reach G0–G1 tomorrow. Factors to monitor include a CME observed on 10 October 2026 at approximately 15:36 UTC time, as well as Coronal Holes #99 and #02, which are facing Earth and may influence near-Earth space weather within the next 1–2 days. ⚛️ Solar Proton Proton flux level: S0 – Quiet Current Status: The proton flux remained relatively stable, with the proton flux at energies >10 MeV remaining below 10 particles/cm²/s·sr, which is below the threshold for a Proton Event. Therefore, no Proton Event occurred, and the proton flux remains at S0 (Quiet). Outlook: The proton flux is expected to remain at S0 (Quiet) over the next day.
