Big Storm on Saturn: Did you get a telescope for Christmas? If so, point it at Saturn. A giant storm even brighter than Saturn’s rings is raging through the planet’s cloudtops. Amateur images and sky maps are featured on http://spaceweather.com.

Geomagnetic Storm in Progress: At the time this post is being published (late afternoon UT on Dec. 29) a polar geomagnetic storm is in progress (Kindex=5). Observers report electric currents in the ground and intensifying Northern Lights over Scandinavia. High-latitude sky watchers should be alert for auroras.
