IHW COMET HALLEY LSPN NON-DIGITIZED IMAGES V1.0

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 data from the Large-Scale Phenomena Network has been organized into a set of digitized images and those left in the original analog state for reasons of quality, time coverage, or submission problems. These latter 1771 pieces of data are held in an archive both at Goddard Space Flight Center and with the Small Bodies Node of the Planetary Data System. (In the latter case, contact specifically the Comet Sub-Node of the PDS at the Laboratory for Atmospheric and Space Physics associated with the University of Colorado Boulder, for more assistance). Some of these analog images are presented in 'The International Halley Watch Atlas of Large-Scale Phenomena' (Brandt, John C., Niedner, Malcolm B. Jr., Rahe, Jurgen, 1992). The data cover a time range from 1984 December 22 through 1987 April 26 through 23 of the IHW Chronological Data Archive Collection
