in de e-mail van vannacht:
EARTH-DIRECTED X-FLARE: Big sunspot AR1520 erupted on July 12th around 16:53 UT,
producing an X-class solar flare and hurling a CME directly toward Earth.
Forecasters expect the cloud to arrive on July 14th. Its impact could spark
moderate to severe geomagnetic storms, allowing auroras to be seen at lower
latitudes than usual. Check http://spaceweather.com for more information and
