        "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 typically indicates dayglow emission, green indicates nightside recombination emission, white streaks typically indicate stars in the instrument field-of-view.",
