    • IHW COMET HALLEY POLARIMETRIC OBSERVATIONS V1.0

    Metadata Updated: October 30, 2025

    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 Photometry and Polarimetry Network collected 884 polarimetric observations for the Polarimetry Subnetwork. The majority of these observations (752) are expressed as 'percent polarization'. These data span the dates from 1985 September 13 through 1986 May 17.
