QUIET

Geomagnetic activity has trended downward to quiet levels following a period of minor unrest. While the solar disk remains active with six monitored regions, current flare output is minimal.

Geomagnetic conditions are expected to remain quiet with Kp levels peaking at approximately 2.67. No significant geomagnetic storms are anticipated, and solar activity will likely persist at these moderate levels without major impulse.

🌌 Aurora

Aurora visibility is not expected at mid-latitudes for the next 24 hours.

more

Observation opportunities are restricted to high-latitude regions, where minor, localized displays remain possible but unlikely given the current lack of solar wind disturbance.

👁 Watch for

Monitor active region evolution for signs of magnetic flux emergence, as the 20% X-class flare probability warrants attention despite current stability.
