X-Ray
A/B (quiet)

Solar activity is currently low, with no significant geomagnetic storms reported or expected in the next 24 hours. While flare probabilities remain elevated due to complex sunspot configurations, actual output remains subdued.

The geomagnetic field is currently quiet with a Kp-index of 1.3, reflecting a stable solar wind environment. Although 29 active regions are present on the disk, X-ray flux remains at background levels. The F10.7 index is hovering near 99 sfu, signaling a moderate density in the solar atmosphere.

Key Metric

The 35% probability for X-class flares is the primary metric to watch, as it suggests the potential for sudden, high-energy events despite the current period of relative calm.

Conditions are expected to stay in the quiet range for the next 24 hours, with the Kp-index likely to settle below 2.0. No significant solar energetic particle events or geomagnetic disturbances are anticipated during this period.

🌌 Aurora Outlook

Aurora visibility is restricted to high-latitude regions, primarily near the poles. Mid-latitude observers should not expect any significant aurora activity over the next day.

Monitor AR4441 for magnetic complexity, as its ‘Eai’ classification suggests it has the structural potential for flare development that could shift the current quiet status.
