diameters up to 300 feet. At night, balloons carry running lights which cause an unusual appearance when observed. Reflection of the sun on balloons at dawn and sunset sometimes produces strange effects. This usually occurs when the balloon, because of its altitudes, is exposed to the sun. Large balloons can move at speeds of over 100 miles per hour when moving in high altitude jet windstreams., These balloons sometimes appear to be flattened on top. At other times, they appear to be saucer Shaped and to have lights mounted inside the bag due to the sun’s rays reflecting through the material of the balloon. The Balloon Control Center at Holloman Air Force Base, New Mexico, maintains a plot on all military upper air research balloons. Another category of UFO evaluations labeled Other includes missiles, reflections, mirages, searchlights, birds, kites, spurious radar indications, hoaxes, fireworks, and flares. Aircraft, satellites, balloons, and the like should NOT be reported since they do not fall within the definition of an unidentified flying object.
