Space Weather News for May 28, 2003 SOLAR ACTIVITY: Big sunspot 365 unleashed a series of powerful X-class solar flares on May 27th and 28th. At least one coronal mass ejection(CME)appears to be heading toward Earth. The CME could trigger auroras when it sweeps by our planet later this week. The sunspot itself is big and impressive; you can see it using safe solar projection techniques.
