NEUTRONS ON A PLANE: Researchers have long known that air travelers are
exposed to cosmic rays on board commercial aircraft. Indeed, pilots are
classified as "occupational radiation workers." Two days ago,
Spaceweather.com and the students of Earth to Sky Calculus took a pair of
bubble chambers onboard a flight from Sweden to the USA and detected a
significant number of neutrons in the passenger compartment. This confirms
that neutrons are an important form of aviation radiation. Read more about
it on today's edition of Spaceweather.com.
 
SOLAR WIND ADVISORY: A hole has opened in the sun's atmosphere and it is
spewing a stream of solar wind toward Earth. The stream's arrival on March
23rd could spark the first auroras of northern spring. Monitor the realtime
aurora gallery for sightings.

each bubble shows where a neutron passed through the chamber and vaporized
a superheated droplet.
