We not known who is the parent body of KCGs but from this witness we 
must presume that there is a periodicity of 6-7 years?
(1985-1993-?-2007-2013) If real it must exist today or in the past a 
jovian comet? Or it only the effect of jovian perturbations with a 
period of 6-12 years? There are special years for KCG with bolids?
Best greetings.
