[meteorite-list] Possible Impact Event on Jupiter?

[Mr EMan]

Right Mark, that holds for ground impacts. The apparent diameter looks roughly 3-5 earth diameters and I don't think we are missing a major planet.  I presume someone will compare this to the known sizes of Shoemaker/Levy-9 to get an estimate since that it the only frame of reference we have for impacts on the gas giants.
