A NLC is observed and photographed at 40o latitude for the first time!by AIM Co-Investigator Dr. Michael Taylor
A spectacular but unexpected event: June 22, 1999!
NLCs are being observed at lower latitudes
AIM Mission Overview, James M. Russell III 5
Aim is addressing key questions about NLCs
Why do they form?
Why do they vary?
Why have they appeared at such low latitudes (~ 40oN) in 3 recent NH summers?
Is there a relationship to global change?
