(nightside) for a complete day mapped onto the globe. It is a composite of the O I 130.4 nm emission (blue), O I 135.6 nm (green), and LBH Short (140 - 150 nm) (red). White color indicates emission from particles in aurora (all colors), pink areas generally indicate particle precipitation (SAA) or solar glint, blue emissions indicate typical nighttime recombination emissions. The GUVI data used here are provided through support from the NASA MOamp;DA program. The GUVI instrument was designed and built by The Aerospace Corporation and The Johns Hopkins University. The Principal Investigator is Dr. Andrew B. Christensen and the Chief Scientist and co-PI is Dr. Larry J. Paxton.
