What the Sun and Earth's Magnetic Shield Are Doing Right Now

Updated Sat Oct 31, 8:58 PM ET from live NOAA satellites

1. NORTHERN LIGHTS TONIGHT

Kp 3.7 / 9

Minor storm level (G1) possible: an outside chance along the northern US border

24-hour peak forecast: Kp 4.7 (Kp 5+ is a storm). Good for high latitudes (Alaska, Canada, Iceland, Norway, Lapland) on clear nights.

2. SOLAR WIND & EARTH'S SHIELD

525 km/s

Moderate Solar Wind (~1,174,394 mph)

Earth's magnetic shield is holding steady at 10.4 Earth radii (~41,215 miles) up on the sunlit side. Solar-wind magnetic direction (Bz): -2 nT (pointing south — helps aurora).
