The impact sparked a G2-class geomagnetic storm and bright auroras around the Arctic Circle. At the time this alert is being written, the storm is still in progress.

AVIATION RADIATION EXPERIMENT: En route to observe the March 9th total eclipse in Indonesia, the students of Earth to Sky Calculus conducted an unusual experiment in aviation radiation. Their plane flew a great circle around the Pacific Ocean, skirting the Arctic Circle and crossing the equator in a relatively short period of time. This allowed them to take a snapshot of onboard cosmic radiation doses over a wide range of latitude. Visit Spaceweather.com for results.
