Eric,

Many thanks, very useful info.

Hopefully others on this list will find the following details
derived from the astrometry useful for setting their scopes on these
fragments, but beware, all these offsets are for the time of the G96
measures (~08h UT on 2nd Apr) and they will get bigger and bigger as
the pieces head towards us in the coming days and weeks.

I've identified likely fragments H & L in the data and included
those already identified by Eric.

The three major components C,B & G are not listed here - this is a
list of offsets from those three, make sure you are offsetting from
the correct object!

G96- ID Mag RA offset Dec from component
