The interplanetary magnetic field is directed southward, leading to
moderate geomagnetic disturbances. The midnight aurora associated with
this activity is now well southward over Russia. Late night aurora was
not visible in Alaska due to forest fire smoke. If the interplanetary
field remains at the present level, there will be aurora visible tonight
(Aug 30) in northern Europe. Indeed, southern Scandinavia should be
seeing aurora now (2030 UT).
We apologize for the lateness of this warning, but there was no solar
event leading to this activity. There was a small solar event today,
the effects of which will not reach earth before Sept 2nd.
If the interplanetary magnetic field remains southward at the present
levels, there will be aurora over the northern half of the USA tonight
(Aug 30).
