IHW Comet Halley Radar Data: 1985 November 28 Observations

NASA's International Halley Watch archive includes radar observations of Comet Halley from a single day in 1985. The data is part of a larger collection spanning multiple scientific disciplines, augmented by spacecraft measurements. The Radio Studies Radar Subnetwork contributed this specific file, which was evaluated by specialist teams for inclusion in the official archive.

Use Cases

• Analyzing comet nucleus properties based on radar reflection data
• Studying the composition and structure of Comet Halley's coma based on radio observations
• Correlating ground-based radar measurements with spacecraft data mentioned in the description
• Researching the 1985-1986 apparition of Halley's Comet for historical astronomical studies

Strengths

• Data originates from NASA's authoritative International Halley Watch (IHW) program.
• Observations are part of a multi-disciplinary archive vetted by specialist teams.
• Includes data augmented by spacecraft measurements.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data is from a single day (1985-11-28); temporal coverage is limited.
