DAYTIME OCCULTATION OF VENUS: On Monday, Dec. 7th, sky
watchers in North America can see the Moon pass in front of Venus in
broad daylight--no telescope required. Visit Spaceweather.com for observing tips and more information.
SOLAR WIND SPARKS AURORAS: Earth is entering a stream
of solar wind flowing from a broad coronal hole on the sun. In
response, auroras are dancing around the Arctic Circle. More lights are
in the offing as Earth moves deeper into the stream. NOAA forecasters
estimate a 55% chance of polar geomagnetic storms on Dec. 7th and 8th. Aurora alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice).
