The interplanetary magnetic field (IMF) around Earth has tilted south, opening a crack in Earth's magnetosphere. Solar wind is pouring in to fuel bright auroras around the poles.<br /><br />The Auroral oval also looks good - with the visibility line as far south as 45 degrees, which is the latitude of Salem. The Planetary K-index is at 6 which is also very good. See http://www.swpc.noaa.gov/products/planetary-k-index Unless this activity subsides we could see auroras as early as 9-10PM. Someone has already posted a photo of aurora visible in Bozeman MT this evening at Spaceweather.com <br /><br />All we have to do is wait for the Pacific NW to rotate under the most intense part of the oval. I am not seeing any yet on the Skunk Bay Webcam.

If you don't see a kp of at least 6, don't expect much of a show this far south =).Chrometrailshttps://www.blogger.com/profile/14472721285710981108noreply@blogger.com
