> 0610Z / 06 MAY AURORAL ACTIVITY SYNOPSIS:
>
>
>Auroral activity was mostly quiet to unsettled over the last 24 hours.
>The arrival of an interplanetary disturbance (possibly the anticipated
>class M4.5/2N flare associated coronal mass ejection disturbance) produced
>periods of slightly enhanced auroral activity over the high latitude
>regions, but nothing of particularly impressive intensity. There remains a
>chance periods of auroral activity could become strong enough to observe
>from middle latitudes. We are watching conditions closely. It appears that
>the Earth is passing through the outer fringes of the disturbance rather
>than through the more influential regions nearer to the core of the
>disturbance. For this reason, the impact and geoeffectiveness of the
>disturbance likely won't reach the levels anticipated. However, the
>potential for periods of stronger enhanced activity will remain possible
>through most of the UTC day of 06 May.
>Thereafter, overall activity should begin to subside.
