Opening your observatory…

Catch the flash twice

Two amateur cameras in Ireland and Austria recorded a brief flash on Jupiter. Inspect what the independent views agree on and what their clocks leave uncertain.

What to keep in mind

The published observer clock estimates differ. Kernbauer's player includes an enlarged replay of the same capture; that replay is not a third observation or a resolved incoming body.

Find the brief flash

Watch Jupiter's edge in McKeon's six-second clip. Distinguish the brief bright feature from the planet's general shimmer and record where it appears.

Check the second camera

Look for the corresponding bright feature in Kernbauer's recording. Which features agree despite different seeing and the enlarged replay?

Bound the impact estimate

Which observations support a real brief flash, and which claims about an impactor's size or mass require calibrated brightness and a physical model?
