THE PUERTO RICO OBJECT
 Analytic Factors: Perception of objects’
fading in and out due to Thermal
Crossover.
 Trajectory reconstruction shows the
objects traveled southwest in a straight
line at a consistent speed of ≈3.6
meters per second while slowly
descending to ≈200 meters.
 Winds were 7 knots (3.6 m/s) out of the
east-northeast. Cloud cover was
approximately 50 percent, with scattered
clouds at 914 meters (3000 feet).
Vector analysis is used to plot the line of sight of the sensor as a function of time. Using a closest-approach
method, a track of the object can be estimated
