QUIET

Current solar activity is stable with the magnetosphere remaining in a quiet state. While geomagnetic conditions are settled, the presence of eight active regions maintains a moderate probability for impulsive flare activity.

Next 24 h

Expect geomagnetic conditions to remain largely quiet through the next 24 hours, with only a slight, transient uptick to Kp 3 early tomorrow morning.

Solar flare potential remains elevated for C-class events, with a non-negligible 70% probability for M-class activity originating from the more complex active regions.

🌌 Aurora

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

more

Observers at very high polar latitudes may see faint, quiet auroral displays, but standard mid-latitude regions should not anticipate significant activity.

👁 Watch for

Monitor active region AR4498 as it rotates further into view; any rapid increase in magnetic complexity could shift our flare potential outlook.
