From Satellites:

Thanks to modern space technology, we can now study solar storms as they arrive at Earth, causing spectacular changes in Earth's magnetic field. This input of energy and matter into Earth's space environment produces many phenomena including the breath-taking dance of the aurora.

If you are just Getting Started, you will be using the ACE (Advanced Composition Explorer) satellite and GOES (Geostationary Operational Environmental Satellites) to find out what the solar wind conditions are like in space. The ACE satellite is about one million miles from Earth. This position between the Sun and the Earth gives us a 30 to 45-minute warning that a solar storm is approaching. The GOES 10 and GOES 12 satellites are about 35,800 km (22,300 mi) and always stay above the same Earth location.

When you feel confident with the ACE and GOES data, you can do More Advanced Observations with the HENA (High Energy Neutral Analyzer) instrument on the NASA IMAGE (Imager for Magnetopause-to-Aurora Global Exploration) satellite.
