POLAR GEOMAGNETIC STORM: Today, March 6th, Earth is entering a stream of solar wind, and the encounter has sparked a G1-class geomagnetic storm. Inside the stream, magnetic fields have a negative polarity--a condition which favors auroras. High-latitude sky watchers should be alert for Northern Lights.

AVIATION RADIATION EXPERIMENT: This weekend, Spaceweather.com and the students of Earth to Sky Calculus are flying to Indonesia to observe the March 9th total eclipse. En route, they are conducting an experiment in aviation radiation. Their flight skirts the Arctic Circle and crosses the equator, allowing them to make cosmic ray measurements over a wide range of latitudes in a relatively short amount of time. Stay tuned to Spaceweather.com to learn the results.
