We have a few more nights of 2.0m observations of this comet. The latest
observations were made by Amelia Davies.

My astrometry of these images indicates a relative drift rate between
fragment B and the main component of 0.171 arcsec/day. The separation is
currently 12.6 arcsec so that implies that the separation took place
around 70 days ago.
