Here Comes the Sun - Watch Out for Auroras Later This Week
10 Oct 2001
A solar explosion on Tuesday (Oct. 9th at 1110 UT) hurled a full-halo coronal mass ejection toward Earth. The expanding cloud, which sped away from the Sun traveling approximately 1000 km/s, could strike our planet's magnetosphere as soon as Thursday, Oct. 11th. Sky watchers, especially those living above geomagnetic latitude 50 degrees, should remain alert for Northern Lights during the nights ahead. The best time to spot auroras is usually around local midnight. Visit SpaceWeather.com for details and updates.
