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. Visit Spaceweather.com for more information and updates.
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.
