Solar and Geophysical Event Reports

Edited Event reports are preliminary solar event reports received at SWPC and manually reviewed and edited by the duty forecaster. SWPC compiles these lists from preliminary reports received from contributing stations.Today's list is updated every 30 minutes at 2 and 32 minutes past the hour. Yesterday's list is updated every 3 hours, and the lists for the past 3 days are recreated daily at 0302 to pick up late additions or changes.

A description of the Event Reports and the information they provide is available here.
