My image tonight shows a new fragment 20 arcsec west and 9 arcsec south of the the main nucleus (component B). The new fragment is around mag 18.8. The residual nucleus, component B, is currently around magnitude 15.2.  The stacks I used for astrometry are here in an animated GIF. Each of these stacks is 15 minutes long so the star trails are around 26 arcsec. The object is the faint dot moving with the comet around 22 arcsec ahead of it.The forecast here for tonight is not encouraging so it would good if other observers could confirm this.
