Next 24 h
Geomagnetic activity is expected to remain unsettled over the next 24 hours, with Kp levels likely oscillating between 3 and 4. No major flaring is anticipated, as the probability for M-class or X-class flares remains very low.
🌌 Aurora
Aurora visibility for mid-latitudes remains unlikely.
more
Observers at high latitudes (above 60°N) may experience brief, localized aurora displays if the Kp index trends toward 4 overnight.
👁 Watch for
Monitor AR4524 as it traverses the disk for any signs of magnetic complexity evolution that could increase its potential for M-class flare production.
