just to make the things more complicated:

fragment_B appears to be currently in outburst and probably
disrupting in smaller fragments that might be observed in the days
ahead.

moreover, MPEC 2006-G10 reports 5 news fragments: u, v, w, x, and y
between mag 19 and 21, which means that 18 fragments have now been
observed.

I think the 73P fragments elements problem is going to be a real
mess...
