QUIET

Solar activity is characterized by moderate flaring from a single active region, while geomagnetic conditions remain stable and quiet. Despite the frequent M-class flares, there are no immediate indications of earth-directed coronal mass ejections.

Expect continued M-class flare activity from AR4513, with a 40% probability of further moderate events.

more

Geomagnetic conditions are expected to remain in the quiet to unsettled range through the next 24 hours as no significant solar wind drivers are currently identified.

🌌 Aurora

Aurora visibility is not expected at mid-latitudes; activity will remain confined to high-latitude regions due to the current lack of strong geomagnetic disturbance.

👁 Watch for

Monitor AR4513 for any signs of complex magnetic evolution that could transition from isolated M-class flares to larger eruptive events.
