QUIET

Solar activity is currently low, with stable geomagnetic conditions and minimal X-ray output. The F10.7 solar radio flux has dropped slightly below 100 sfu, indicating a period of reduced atmospheric ionization.

Geomagnetic activity is expected to remain at quiet levels, with Kp indices hovering between 1 and 2 throughout the next 24 hours.

more

No significant solar radiation storms or radio blackouts are anticipated, and flare activity will likely stay limited to low-level C-class events.

🌌 Aurora

Aurora visibility is not expected at mid-latitudes.

more

The current solar wind environment provides insufficient energy to drive significant auroral displays beyond the high polar regions.

👁 Watch for

Monitor AR4513 for any sudden increases in magnetic complexity, as it holds the highest probability among current regions to generate more frequent C-class or low-level M-class flares.
