Next 24 h
Geomagnetic conditions are expected to remain quiet with Kp values holding steady at approximately 1.3.
more
No significant solar wind streams or coronal mass ejections are currently Earth-directed, ensuring stable conditions for satellite operators and power grids.
🌌 Aurora
Aurora activity is currently confined to high-latitude regions and is unlikely to be visible at mid-latitudes.
more
Observers in northern regions should expect only faint or localized displays.
👁 Watch for
Monitor AR4523 for any growth in magnetic complexity, as it is the most likely candidate for potential M-class flare activity.
