Where do meteor showers originate?
To help answer this question, astronomers studied in some detail the
Quadrantid meteor shower
that occurred over this past weekend.
In particular, astronomers with specialized cameras flew as part of the Quadrantid's
Multi-Instrument Aircraft Campaign (MAC) aboard a
Gulfstream V aircraft above northern
Canada over the past few days and studied the

Visible in the image are the wingtip of the airplane
reflecting a red beacon on the left, green aurora most prominent on the

are that the meteor stream is quite stable in time but variable in meteor abundance.
Over 100 meteors per hour were visible at the peak from the MAC aircraft.
Meteor data from around the world will continue to be analyzed to try to verify
Peter Jenniskens's recent
minor planet2003 EH1 is an intermittently
active comet and the parent body of the annual
Quadrantid meteor shower.
