Combined ground-based optical support for the aurora (DELTA) sounding rocket campaign
The Japan Aerospace Exploration Agency (JAXA) DELTA rocket experiment, successfully launched from Andoya at 0033 UT on December 13, 2004, supported by ground based optical instruments, primarily 2 Fabry-Perot Interferometers (FPIs) located at Skibotn, Norway (69.3 degrees N, 20.4 degrees E) and the...
