Next 24 h
Geomagnetic conditions are expected to remain quiet with the Kp-index hovering between 1 and 2. No significant geomagnetic storms are anticipated, and radio propagation should remain within nominal parameters for the next 24 hours.
🌌 Aurora
Aurora activity is currently restricted to high-latitude polar regions.
more
Mid-latitude observers are unlikely to see any displays given the low Kp-index and lack of incoming solar wind drivers.
👁 Watch for
Monitor the development of AR4524 as it transits the solar disk, given its capacity for recent M-class flare production.
