Next 24 h
Geomagnetic conditions are expected to remain quiet with Kp values fluctuating between 1.0 and 2.3. No solar radiation storms or radio blackouts are anticipated as the potential for M-class or X-class flaring remains very low.
🌌 Aurora
Aurora activity will be restricted to typical high-latitude regions near the poles.

There is no expectation of mid-latitude aurora visibility during this period.
👁 Watch for
Monitor for any sudden evolution in the magnetic complexity of the current active regions that could elevate the risk of C-class flares.
