From S & T's AstroAlert for Sun-Earth Interactions:
An earthward directed coronal mass ejection is expected to increase levels of auroral activity early in the UTC day of 05 December (very late evening hours of Saturday night or very early morning hours of Sunday morning over North America). Activity has the potential to become sporadically strong over isolated regions. Observations from locations equatorward of the lines noted above are also possible in isolated regions. Observers are encouraged to watch the skies over the next few nights for possible northern lights activity.
This watch will remain valid through 23:00 UTC (6 pm EST) on 06 December. It will then be allowed to expire. For updated information, visit: http://www.spacew.com/aurora/forum.html . For real-time plots of current activity, visit: http://www.spacew.com/plots.html or http://www.sec.noaa.gov .
