The Project Twinkle Final Report, approved 27 November 1951 by Louis Elterman of the Air Force Geophysics Research Division's Atmospheric Physics Laboratory, describes a camera and observation program begun in 1950 to investigate green fireballs and other light phenomena over New Mexico, at Vaughn and Holloman AFB. It says the findings were essentially negative and puts most sightings down to aircraft, balloons, birds, planets, meteors or clouds. It recommends no further spending, with meteor camera film to be checked instead.

# ```markdown ``` These data then would be used to demonstrate the need for initiating a study of the phenomena. On 21 February 1950, an observation outlook post was set up at Holloman Air Force Base manned by two personnel. Observations with theodolight, telescope and camera were undertaken between the hours of sunrise and sunset. On 5 March 1950 a conference was held at Wright-Patterson Air Force Base which included Holloman Air Force Base and GRD personnel. Action was taken to initiate a three point program which was confirmed by AMC in the form of a letter directive on 16 March 1950, subject "Light Phenomena". a. Askania instrument triangulation by Land-Air Inc. b. Observations with Mitchell camera using spectrum grating by Holloman Air Force Base personnel. c. Electromagnetic frequency measurements using Signal Corps Engineering Laboratory equipment. Under contract to GRD, Land-Air Inc. was required to maintain constant watch at two Askania stations for a six-month period. Since an abnormal number of reports had been received from Vaughn, New Mexico, it was decided to install the instrumentation at Vaughn.
