The NOAA has posted an alert of a potential geomagnetic storm hitting the Earth today, the result of a coronal mass ejection. These usually create the light show called Aurora borealis visible in the night skies at locations closer to the Earth's magnetic poles. You might want to unplug your tech because of the possibility of high voltage transients on the transmission lines.
For those interested in astronomy, if you're looking for a good phone application to identify celestial objects, I tried using SkEye on my phone last night and the sky map aligned with the sky in whatever direction I held the map up and allowed me to instantly identify the brightest objects and all the constellations visible to the naked eye from my location. However, it is possible that the geomagnetic storm could interfere with or damage the geo positioning satellites.
