sfu · >150 = high activity

The sun is exhibiting low-level activity with several active regions present, producing only minor C-class flares. Geomagnetic conditions are stable with a Kp-index of 1.7. Solar radiation flux remains at moderate levels, indicating a lack of high-energy proton events.

Key Metric

The Kp-index of 1.7 confirms a stable magnetosphere with minimal risk of interference to satellite operations or power grids.

Expect geomagnetic conditions to trend slightly upward toward Kp 3 as we head into the next 24 hours. Flare probability remains weighted toward C-class events, with no significant solar radiation storms anticipated.

🌌 Aurora Outlook

Aurora visibility remains confined to high-latitude regions. Observers at mid-latitudes are unlikely to see activity given the current and forecast geomagnetic indices.
