SYNOPSIS...

A very vigorous interplanetary disturbance impacted the Earth near
16:04 UTC on 06 April. Although we are still in the initial phase of this
disturbance, it appears conditions may be setting up nicely for the
generation of a minor to major auroral storm. Widespread observations of
auroral activity throughout northern Europe and the U.K. may be possible.
There is also a good chance periods of activity may become visible throughout
many middle latitude regions of the night-sectors of North America.
