Solar activity is currently characterized by moderate flare production from AR4513, while geomagnetic conditions remain largely unsettled. The planetary K-index is trending upward, reaching 3.3, but has not yet reached storm levels.
⚠ X-ray flare M5 summary · 4 more below
Geomagnetic activity is expected to climb, reaching Kp 4 (unsettled) by the start of August 21st.

The probability of further M-class flares remains at 55%, suggesting potential for brief, minor radio interference on the sunlit side of Earth.
Aurora visibility is not currently expected at mid-latitudes.

Observers in high-latitude regions (above 60°N) may experience minor activity, but clear conditions at these latitudes are the most critical factor for viewing.
Monitor GOES X-ray flux for any further M-class flare signatures originating from AR4513, which could signal more significant solar disturbances.
