GEOMAGNETIC STORM WARNING
_________________________________________________________
On 19 January there was an M3.2 X-ray solar flare and
an associated full-halo Coronal Mass Ejection (CME). We expect
this CME to strike Earth's magnetosphere in the next 24 to 36 hours.
Following this event there is an increased risk of a geomagnetic
STORM from late on 21-JAN to 22-JAN (UK time). There is also an
increased chance of viewing the aurora borealis (or australis)
during local night-time hours, assuming dark and clear skies,
though this is dependent on the configuration of the interplanetary
magnetic field (IMF) embedded in the solar wind.
