The storm has entered its main phase and it has strengthened to the expected G3 (Strong) level.  Solar wind conditions suggest that this activity will continue for many hours and aurora watchers should be in for a good treat.  SWPC forecasters will be monitoring conditions and will be ready to issue warnings should more intense storming occur.  Stay tuned here for updates.
