Abstract:
The effect of SL9 impact on Jupiter has been assessed by observing flash-light effect on the nearest satellite of Jupiter, the Io, on 21 July, 1994. The observations in V filter of flash-light effect on Io suggest a considerable brightening of more than 2 magnitudes as compared to the normal brightness of Io. Three distinct peaks of brightening are visible in the light curve which indicate three collision events. The mass of the fragmented nuclei undergoing impact with Jovian surface is estimated to be slightly greater than 1013 kg.
