Solar activity is currently quiet, but geomagnetic conditions are forecast to reach G1 (minor storm) levels within the next few hours due to an incoming solar wind stream. The Sun remains in a moderate state with an F10.7 flux of 124 sfu.
⚠ Electron flux F3 reached · 4 more below
Expect geomagnetic conditions to rise to Kp 4.67 (G1) between 18:00 UTC today and 00:00 UTC tomorrow. Activity is expected to subside back to quiet levels by early October 3rd as the influence of the current solar wind disturbance wanes.
Auroral displays are unlikely for mid-latitudes (40-60°N).

While the G1 threshold may briefly elevate the chances of sightings in far northern regions like northern Scandinavia or parts of Canada, observers at lower latitudes should not expect significant visibility.
Watch for the transition in Kp-index readings after 18:00 UTC to confirm if the anticipated solar wind speed increase matches the forecasted geomagnetic impact.
