GEOMAGNETIC STORM: Earlier today, the outskirts of a CME previously
expected to miss Earth instead hit. 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. Visit

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
