Space Weather

Haven't you ever wondered what an ion storm is, much less where one might come from? While http://www.spaceweather.com/won't answer that specific question, it provides plenty of fascinating solar weather data - sun spot activity, solar wind, auroral activity and even for the next day or two, the expected trajectory of the space shuttle transiting the continental US on its return from the space station. Still. It's time to find out whether interstellar travel is subject to phenomena that we'd perceive as weather.
