Energy-deposition profile of a 16-m diameter ice impactor entering Jupiter’s atmosphere in terms of atmospheric height a) and time b). The rapid increase in the deposited energy at 120 km indicates the initial breakup of the object, and the sharp peak at about 100 km altitude represents the disintegration of the last big coherent fragment. The time behavior of energy release compares well with the light curves analyzed in the three impacts. Significant structure in the synthetic light curve is found in time scales of 0.05 s, suggesting an ideal time-resolving observation of 20 frames per second. A Gaussian fit to the energy release in terms of time appears in panel b). The FWHM of this fit is 0.35 s. The bright explosion is followed by further release of energy when the rests of the impacting object desintegrate 90 km above the 1 bar level. This behavior seems similar to the one present in the light curves from the June 2010 and August 2012 impacts.
