QUIET
Solar activity remains at low levels with the planetary K-index holding steady at Kp 1.0. While multiple active regions are present, flare output has been limited to low-level C-class events.

Next 24 h
Geomagnetic conditions are expected to remain quiet over the next 24 hours, with the Kp index likely not exceeding 2.0. No significant geomagnetic storms are anticipated, and the interplanetary medium remains stable.
🌌 Aurora
Aurora visibility is restricted to high-latitude regions near the poles.

There is no expectation of activity reaching mid-latitudes (40-60°N) at this time.
👁 Watch for
Monitor the magnetic evolution of AR4498 and AR4499 for any signs of flux emergence that could trigger a transition from C-class to M-class flaring.
