 An international Steering Group was established, and a set of Discipline Specialists was chosen to organize observing networks, coordinate their activity, and ultimately to collect and archive their data.This effort was endorsed by the International Astronomical Union in 1982, and cometary scientists were chosen as Discipline Specialists in the areas of Astrometry, Infrared Studies, Large Scale Phenomena, Near-Nucleus Studies, Photometry and Polarimetry, Radio Studies, Spectroscopy and Spectrophotometry, Meteor Studies, and Amateur Observations.The IHW also coordinated with the space missions to the comet, Giotto by the European Space Agency and Vega by the Soviet Union and collaborating countries.
