Colorgramme WMeteor is a specialized, free radio astronomy software designed to visualize and map radio meteor observations. It works alongside meteor detection software to process data from amateur radio meteor scatter setups.
Here is a comprehensive overview of what the software does, how it functions, and its role in amateur radio astronomy: Core Function and Purpose
When a meteor enters the Earth’s atmosphere, it leaves behind an ionized trail of particles that temporarily reflects radio waves. This phenomenon is known as “meteor scatter”. Colorgramme WMeteor serves as a “backend” data visualizer. It takes the recorded radio echoes of these falling stars and translates them into readable graphs, charts, and sky maps. Key Features
WMeteor Sky Map: A built-in feature that maps the sky directly over your radio antenna based on your specific latitude and longitude. It displays constellations, stars, the moon, and planets, refreshing automatically every three minutes.
Shower Visualizations: It plots major annual meteor showers using data compiled by the International Meteor Organisation (IMO). The software highlights active showers proportionally to their Zenithal Hourly Rate (ZHR), turning them red when they reach peak activity and using fuchsia specifically for radio meteor showers.
Antenna Alignment: It draws the exact axis of your directional antenna as a yellow circle with a cross directly on the sky map. This helps observers visually cross-reference which part of the sky their hardware is monitoring against passing meteor streams.
Time Adjustment: Includes an “Hour Step” tool to adjust from Universal Time (UT), allowing you to review past data or simulate the sky layout ahead of real-time PC clock stamps. Ecosystem and Data Sharing
Colorgramme acts as an essential reporting bridge for the amateur radio community. It processes specific raw text and index data files generated by detection software (such as Meteor DOS, MAnalyzer, or HROfft). Colorgramme WMeteor version 1.0
