Next 24 h
Geomagnetic activity is expected to stay quiet over the next 24 hours, with Kp values projected to remain below 2.0. Solar flare probability remains moderate for C-class events, but the likelihood of M or X-class activity is low.
🌌 Aurora
Aurora visibility is not expected at mid-latitudes; activity will be restricted to typical high-latitude locations such as the auroral oval, where only baseline auroral displays are likely.
👁 Watch for
Monitor the magnetic evolution of AR4520, which remains the most complex region despite its current quiet state.
