Continued Solar Activity Triggers a Weekend Aurora Watch
Continued Solar Activity Triggers a Weekend Aurora Watch
7 Apr 2001

Solar activity remained high on Friday as active region 9415, a sunspot group about the five times the size of Earth, unleashed a powerful X5-class solar flare. The explosion hurled a coronal mass ejection (CME) into space -- and somewhat toward Earth. Friday's CME joins another one already en route toward our planet. The pair could trigger auroras (most likely at high latitudes) when they strike Earth's magnetosphere this weekend. Stay tuned to for updates.
