Observers at high latitudes (above 60°N) may experience brief, low-level displays as the K-index approaches 4.67 later this evening.

👁 Watch for

Monitor the 21:00 UTC transition to see if the Kp threshold of 5 (G1 storm level) is breached, which would signal a shift to more active geomagnetic conditions.
