While M-class flare probability remains at 50%, no immediate impacts to satellite or power grid infrastructure are anticipated.
🌌 Aurora
Aurora visibility is restricted to high-latitude polar regions.

Mid-latitude observers should not expect any significant auroral displays during this period.
👁 Watch for
Monitor the magnetic complexity of AR4493 and AR4494, as their configurations suggest a 50% probability for M-class flare activity in the coming day.
