[Geysers] Auroras in YNP tonight or tomorrow?

[Freund, Udo]

NASA announced this afternoon that a solar eruption involved an M2 (medium-sized) solar flare, an S1-class (minor) radiation storm, and a spectacular coronal mass ejection (CME) from sunspot complex 1226-1227. After ballooning high above the Sun, the large cloud of matter rained back down onto an area covering almost half the solar disk.  There is a video @ URL http://www.skyandtelescope.com/observing/home/123377553.html

The CME should deliver a glancing blow to Earth's magnetic field during the late hours of June 8th or 9th. High-latitude skywatchers should be alert for auroras when the CME arrives.

Will auroras be visible from Yellowstone?  Let us know, please, if you see them.

Thanks,
Udo Freund
