NASA's International Halley Watch (IHW) has created a Comet Halley Archive. The collection of data spans the full wavelength range as submitted by scientists to the IHW. The observations belong to one of the following Disciplines: Amateur, Astrometry, Infrared Studies, Large-Scale Phenomena, Meteor Studies, Near-Nucleus Studies, Photometry and Polarimetry, Radio Studies, and Spectroscopy and Spectrophotometry. The data collected by these nine disciplines were augmented by Spacecraft measurements. The data were submitted to IHW, but the evaluation and selection for the Archive has been the primary responsibility of the Discipline Specialist Teams for each network in cooperation with the Lead Center. The Infrared Imaging subnetwork contains 66 images of Halley and 29 images of calibration stars (HD18881, HD3029, HD10560, HD10696, HD12965, BS134, BS923, BS1856, Beta Pegn Rho Ori) for dates spanning 1985 March 11 through 1986 May 23.
