GEOMAGNETIC STORM WARNING
_________________________________________________________

Following recent observations of solar activity there is an
increased risk of a geomagnetic storm from 24-JAN-2012 to
25-JAN-2012.

An energetic M-class solar flare erupted on the Sun earlier today.
This was associated with a coronal mass ejections (CME) that is
expected to arrive at Earth tomorrow.

There is an increased chance of viewing the aurora during
local night time hours assuming dark and clear skies, though this
is dependent on the configuration of the interplanetary magnetic
field embedded in the solar wind.
