Middle Latitude Auroral Activity WARNING
Issued: 2:30 UTC, 11 March 2012
Solar Terrestrial Dispatch

The next major solar disturbance is expected to impact the Earth within
the next 12 hours or so. Its arrival is expected to produce another round
of auroral storm activity that could become visible well into the central
middle latitude regions and possibly the lower latitude regions (areas
from southern Canada and south into the central United States and possibly
areas further south).
At least two additional coronal mass ejection have been determined to be
Earthward-directed over the last 24 hours and will prolong periods of
auroral activity well into 13 March. Activity thereafter will likely
subside to quiet levels as the solar region responsible for the disturbed
conditions rotates behind the western solar limb and out of view.
The best opportunity to observe activity will likely be during the next 48
hours.
