Active Regions
6
X-Ray
A/B (quiet)

Solar activity is currently stable with a quiet geomagnetic field. While several active regions are visible on the disk, they are producing minimal solar flare activity.

F10.7 Solar Flux

sfu · >150 = high activity

The sun is exhibiting low activity, with an F10.7 flux of 104.0 sfu and X-ray levels remaining in the A/B range. The geomagnetic field is calm, with a Kp-index of 2.3 reflecting no significant solar wind disturbances. Nine active regions are present on the solar disk, but none are currently displaying magnetic complexity capable of triggering major flares.

Key Metric

The current Kp-index of 2.3 confirms a stable magnetosphere, ensuring no disruptions to satellite or radio operations from space weather at this time.

Geomagnetic conditions are expected to remain at quiet levels, with Kp values forecasted to stay below 2.0. Solar flare activity will likely persist at low levels, with a 95% probability of C-class flares and a moderate 35% chance of M-class activity as regions rotate across the disk.

🌌 Aurora Outlook

Aurora activity will be confined to the high polar latitudes. Mid-latitude observers should not expect any visible auroral displays under current conditions.
