        "Description": "This composite image is produced from GUVI radiance data (Level 1C) plotted as a strip image for a complete day. 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, light grey typically indicates dayglow emission.
