Possibility of aurora tonight, Sunday 17th March 2013

Following a large Coronal Mass Ejection (CME) impact earlier today, there is a possibility of aurora tonight.

At the time of writing the KP index is measuring 6. The higher the number, the more likely we are to see an aurora. KP=6 means there’s a possibility. If it gets to 7 above the likelyhood increases a lot.

Keep an eye on SpaceWeather.com and the Auroral Ovation Oval at the NOAA Helios website.
