    No significant space weather events or disturbances to satellite operations or power grids are anticipated during this period.

    🌌 Aurora

    Aurora visibility is restricted to high-latitude polar regions.

    more

    Mid-latitude observers should not expect any auroral activity under these current geomagnetic conditions.

    👁 Watch for

    Monitor AR4513 for any rapid increases in magnetic complexity, as it currently holds the highest potential for C-class or M-class flare production.
