The orbital characteristics of the Grande Prairie fireball of February 22, 1984 are analyzed based on photographic data. Photographs of the fireball were obtained at four separate observation stations in the Meteorite Observation and Recovery Project (MORP) network of the National Research Council of Canada. An entry velocity of 26.5 km/s was obtained from the photographic data, together with an orbit of typical size and low inclination and a small perihelion distance of 0.515 AU. An initial mass of 540 kg is inferred from the dynamical mass near the middle of the flight. Extrapolation of the path indicated a terminal mass of only 12 kg at explosion. The light curve from the photographic records suggests a peak absolute magnitude near -15. Some possible areas for meteorite recovery are recommended. A black and white photograph of the fireball is provided.
