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.

Above: In this photo, taken 35,000 feet above Greenland on March 16, 2017, each
bubble shows where a neutron passed through the chamber and vaporized a
superheated droplet.
