QUIET

Geomagnetic activity is currently stable at quiet levels with a Kp-index of 2.0. While the solar disk remains relatively calm, a 70% probability for M-class flares suggests a need for ongoing monitoring of active regions.

Geomagnetic conditions are expected to remain at Kp 2.0 throughout the next 24 hours.

While the baseline activity is quiet, there remains a persistent 70% chance of M-class flares which could lead to isolated, minor radio degradations on the sunlit side of Earth.

🌌 Aurora

Aurora activity is currently restricted to high-latitude regions.

more

Observers at mid-latitudes are unlikely to see displays during this quiet period, as current solar wind parameters do not favor significant auroral expansion.

👁 Watch for

Monitor AR4498 for any rapid increase in magnetic complexity, which could signal a higher likelihood of significant impulsive solar flares.
