Anthony Wesley in Australia says he saw another impact on Jupiter today- this time capturing the immediate flash on video. No obvious aftereffects, so far, but Europeans and Americans with telescopes might want to take a look tonight...

Lightning has been observed on Jupiter before, but only by spacecraft that are both there, and looking at the planet's night side.
Jovian lightning simply isn't strong eough to view from across the solar system (with current technology at least), and especially in the illuminated hemisphere. -------------------- -- Hungry4info (Sirius_Alpha)

Jovian lightning simply isn't strong eough to view from across the solar system (with current technology at least), and especially in the illuminated hemisphere. Do you know of a paper or report where someone has done the sums and concluded that it would simply be too faint? Remember, Jupiter is 5 times as far away from the sun as the Earth, hence its surface brightness, given the same albedo, should be 25 times fainter than that of the Earth. The answer to the question is not obvious. We need a jovian lightning expert.. |
