> 0545Z / 04 MAY AURORAL ACTIVITY SYNOPSIS:
>The middle latitude auroral activity watch was cancelled today.
>Auroral activity remained fairly dormant with only sporadic and isolated
>periods of mild enhancements over the high latitudes. The anticipated
>coronal mass ejection disturbance failed to materialize.
>Today, a class M4.6/2N solar flare (suspected proton flare) erupted off
>the Sun and was associated with a halo (Earth-directed) coronal mass
>ejection. We believe the disturbance may impact the Earth late on 05
>May or on 06 May. It is possible this disturbance could energize the
>auroral zone to levels capable of producing auroral activity over the
>middle latitudes. We expect to have modelled this disturbance better over
>the next 12 hours and should be able to present a more confident forecast
>in tommorrows report.
>At the present time and based on current data, we believe this disturbance
>might bear watching closely. A middle latitude auroral activity watch
>will likely be issued for this event over the next 24 hours.
