Geomagnetic Disturbance Alert

There is an increased chance of viewing the aurora on 4th/5th December 2017.

A high speed solar wind stream from a recurrent coronal hole is expected to arrive at Earth later on the 4th December. Effects from this coronal hole are expected to continue over the next two to three days.
 
On previous occasions this coronal hole has produced minor storm activity. Therefore we anticipate geomagnetic storm conditions again over the next couple of days. Periods of STORM G1 are likely, with a possibility of some occasional STORM G2.


Assuming clear dark skies there may be an increased possibility of seeing the aurora, with those in more northern parts of the United Kingdom having the best opportunities, although the presence of the full moon may have some negative impact on observing chances.
