One flash, three camera bands
A small telescope in Kyoto caught a bright flash on Jupiter. Compare the observer’s labelled camera channels, then separate the recorded light from the later entry model.
What to keep in mind
The Gh channel uses an instrumental reflection of the same scene, not a second impact. Absolute timing is uncertain by a few seconds. Entry angle, material and energy are model-dependent estimates, not directly resolved properties of the incoming body.
Follow one band
Choose one labelled channel and follow the bright point from appearance to fading. Which changes can you describe from the recording, and which measurements require calibrated frames rather than the player’s displayed brightness?
Recognise the ghost channel
Compare the flash across V, Gh and methane-band views. Why does a matching signal in the ghost channel belong to the same optical scene rather than provide an independent camera confirmation?
Separate flash and entry model
Can the unresolved bright point reveal the incoming body’s composition or entry angle directly? Identify what the later shallow-entry model must explain and which extra assumptions connect light to a physical impactor.
