QUIET

Solar conditions are currently quiet, characterized by low-level flare activity and a stable F10.7 flux of 124 sfu. A modest increase in geomagnetic activity is anticipated within the next 24 hours as solar wind conditions evolve.

Geomagnetic conditions are expected to reach the unsettled Kp 4 level by 12:00 UTC on October 2nd.

No significant radio blackouts are anticipated, though there is a 60% probability of isolated C-class flares as the active regions transit the solar disk.

🌌 Aurora

Aurora visibility is not expected at mid-latitudes (40-60°N) under current Kp 1-4 conditions.

more

Observers at high polar latitudes may see minor activity as the Kp-index trends toward 4.0 later today.

👁 Watch for

Monitor AR4545, currently at N20E61, as its evolving magnetic complexity remains the primary source for potential higher-intensity flaring.
