- THE FIGURE
- Hydra is commonly pictured as the Water Snake.
Begin with Alphard. Follow the connected stars to reveal the figure. - THE PATTERN
- The Water Snake
An artistic interpretation of the constellation figure. The illustration is not a historical artefact; other sky traditions use different figures and stories.

- SEASON
- Catalogue reference streamRepresentative solution; consult a current observing calendar.
The traditional shower name identifies a region of apparent radiation. Its meteoroids are within the Solar System.
Name association is not a claim that the radiant always lies inside modern constellation boundaries. Animation is illustrative, not an activity forecast.
The four animation stages compare illustrative activity. They are not measured rates or this year’s forecast.

A constellation is an area of sky, not one coordinate.
About this sky & sources +
Catalogue stars and traditional line patterns share one celestial projection. Terrain and mythological figures are original artistic interpretations.
Art preserves the composed scene. Horizon uses the labelled reference location and time and true cardinal directions, with a level mathematical horizon. Its continuous illustrated panorama is an imagined setting, not surveyed terrain.
Catalogue coordinates use J2000 and are precessed to the scene date. Weather, moonlight, terrain obstruction and atmospheric refraction are not modelled. This is a learning view, not an observing forecast.
Artwork: original generated illustrations for KamCosmos, including reused locally produced figure layers. Star catalogue and linework: d3-celestial; BSD notice retained in this page.
