QUIET

The Sun is currently in a quiet state with geomagnetic conditions remaining at Kp 1.0. While solar activity is physically active with multiple sunspot regions, no significant flares or Earth-directed disturbances are currently observed.

Geomagnetic conditions are expected to remain quiet with Kp levels hovering around 2.0.

While there is a 70% probability of M-class flares due to the magnetic complexity of current regions, the probability for Earth-impacting coronal mass ejections remains low.

🌌 Aurora

Aurora visibility for mid-latitudes (40-60°N) is not expected.

more

Observers in high-latitude regions may see minimal activity, but quiet conditions currently offer little opportunity for displays beyond typical polar auroral ovals.

👁 Watch for

Monitor the magnetic evolution of AR4498 and AR4499, as their ‘beta-gamma’ magnetic configurations provide the best environment for sudden M-class flare production.
