The meteoroid above Mediterranean Sea on July, 6th 2002 was a fragment of a cometary nucleus?

It is shown, that the explosion of the bolide above the Mediterranean sea on July, 6th 2002 with a high probability was a fragment of an icy cometary nucleus which initial weight was equal approximately to 7 . 10(8) grams. This follows from the determined energy of the outburst equal to 26kT of TNT (Brown et al. 2002). We think that this energy refers to the height of the maximal braking of the body in the Earth's atmosphere. At the speed of 20.3km/s accepted by authors, the weight of a body at this height is equal 5 . 10(8) gr, and at the entrance in the atmosphere it was approximately of 7 . 10(8) gr.
