QUIET

Solar activity remains at low levels with no significant geomagnetic disturbances expected. The sun is currently in a steady, quiet state suitable for routine satellite operations and communications.

Geomagnetic conditions are expected to remain quiet, with Kp levels likely to trend downward toward 0.67 over the next 24 hours.

Flare activity will likely persist at low levels, with a 90% probability of continued C-class production but a low 5% chance of major X-class events.

🌌 Aurora

Aurora visibility is not expected at mid-latitudes.

more

Activity is limited to high-latitude polar regions where only weak, baseline auroral displays may occur.

👁 Watch for

Monitor AR4513 for any sudden increase in magnetic complexity, as its current configuration holds the highest potential for evolving into a more active flare-producing region.
