What's in the sky tonight?
September 13, 2014
-As predicted, a pair of CMEs hit Earth's magnetic field in quick succession on Sept. 11th and 12th. The result was a G3-class geomagnetic storm, the most intense of the year so far. At the peak of the storm on Sept 12-13, bright auroras ringed the Arctic Circle and spilled down over several northern-tier US states. The sky over Maine exploded in a rainbow of colors. "I took the picture from Casco, Maine, facing north towards the Presidential Range in New Hampshire," says photographer John Stetson. "Red, purple, green, blue--all the colors were there!"
The storm is subsiding now. Nevertheless, high-latitude sky watchers should remain alert for auroras. NOAA forecasters estimate a whopping 90% chance of additional polar geomagetic activity on Sept. 13th as Earth passes through the wake of the double CME.
Sky watchers should remain alert for auroras.
-On Sept. 12th, Spaceweather.com was offline for more than 12 hours during the most intense geomagnetic storm of the year. Ironically, the outage was not caused by solar activity. A hardware failure in the network of our Internet service provider brought the web site down at the worst possible time. Webmaster Dr. Tony Phillips apologizes to our readers, alert subscribers, and advertisers for the outage. We are taking steps to make sure this cannot happen again.

Now, as you sip your cosmic latte you can view 100 Hubble Space Telescope images at the same time. The popular scenes of the cosmos as captured from low Earth orbit are all combined into this single digital presentation. To make it, Hubble's top 100 images were downloaded and resized to identical pixel dimensions. At each point the 100 pixel values were arranged from lowest to highest, and the middle or median value was chosen for the final image. The combined image results in a visual abstraction - light from across the Universe surrounded by darkness. Hubble's Top 100 images: http://www.spacetelescope.org/images/archive/top100/
