Solar Prominence!

On Tuesday and Wednesday (Nov. 13 and 14), space weather conditions sparked a geomagnetic storm that supercharged the Earth’s auroras, creating spectacular northern lights displays for observers at high latitudes.

When aimed directly at Earth, the most powerful solar flares and eruptions can pose a threat to satellites and astronauts in orbit, and also interfere with communication, navigation and power systems on the ground.

The sun is currently in the middle of an active phase of its 11-year solar weather cycle. The current cycle is called Solar Cycle 24 and is expected to peak in 2013.
