Asteroid (3944) Halliday

Anonymous's picture

Named in honour of Ian Halliday, an astronomer at the Herzberg Institute of Astrophysics, National Research Council of Canada. Halliday achieved international recognition in three major areas of research in meteoritics: spectroscopy, dynamics and meteorite recovery. He was the first to identify the auroral green line in the spectra of meteors; he planned and directed a large Canadian camera network called the Meteorite Observation and Recovery Project (MORP) and together with his staff determined the definitive photographic orbits of 360 fireballs; and while leading a search party Halliday found the first and largest piece of the Innisfree meteorite, one of only three meteorites recovered entirely on the basis of network photography. Halliday was able to identify six photographic trails with the corresponding six largest Innisfree fragments discovered in the fall area - a unique achievement. He also used MORP data on Geminids to study the minor planet 3200 Phaethon. Halliday served as editor of the Journal of the Royal Astronomical Society of Canada and as President of the RASC.
