EVENING CONJUNCTION: When the sun sets tonight, go outside and look east for Jupiter and the Moon. The two bright heavenly bodies are only 4o apart, a beautiful conjunction and a nice way to end the day. Images: #1, #2.
FARSIDE ERUPTION: Departing sunspot AR1384, currently located just behind the sun's western limb, erupted today around 14:45 UT. NASA's Solar Dynamics Observatory photographed the debris flying over the edge of the solar disk:
The eruption appears to be connected to magnetic filaments snaking over the horizon to the Earthside of the sun. Will this event affect our planet? Probably not. It is located too far from disk center. Stay tuned, however, to see what kind of CME the blast produced.
