QUIET

Current solar conditions are quiet with the geomagnetic field remaining undisturbed. An M-class flare occurred within the last two hours, but no associated coronal mass ejections have triggered Earth-directed impacts.

Next 24 h

Expect geomagnetic conditions to remain quiet, with Kp indices hovering between 1.0 and 2.0 throughout the next 24 hours.

While the probability of C-class flares is high, the overall environment is not conducive to significant terrestrial interference.

🌌 Aurora

Aurora visibility for mid-latitudes is currently null.

more

Quiet geomagnetic conditions mean auroral displays will be confined to their typical high-latitude polar regions.

👁 Watch for

Monitor AR4494 for any signs of magnetic flux emergence or impulsive activity that could escalate the X-ray flare output.
