A NEW HOLE IN THE SUN'S ATMOSPHERE: Get ready for more auroras. A new hole in the sun's atmosphere is turning toward Earth. NASA's Solar Dynamics Observatory photographed the structure in a false-color UV image taken on Sept. 14th. "Coronal Holes" are regions where the sun's magnetic field opens up and allows solar wind to escape. The interior of the hole is black because the hot glowing gas normally contained there is missing. It's on its way to Earth. Minor G1-class geomagnetic storms are possible when the gaseous material arrives on Sept. 16th or 17th. Deepening autumn darkness will favor the visibility of auroras around the Arctic Circle and possibly at lower latitudes, too, if the storm intensifies to category G2. On Sept. 11th, a similar solar wind stream sparked a G2 storm with auroras over northern-tier US states such as Wisconsin and Minnesota. It could happen again in a few days. http://spaceweather.com/ http://www.solarham.net/ Clips, images credit: NASA/JPL, SDO & spaceweather.com Music credit: YouTube Audio Library Cry - Vibe Tracks
