Hi all,

We've been able to get some really high-quality data from the the 2.0-m,
f/5.2 R-C telescope on Haleakala (F65) courtesy of the BAA Work
Experience programme that is currently being led by Helen Usher.

I've measured astrometry of the B component relative to the main comet
photocentre using images obtained with this telescope on three nights.
The observers for the BAA were V. Parakonna and D. Benjamin. The
best-fit linear separation rate is 0.18 arcsec/day.

The B component is visible in smaller telescopes and daily images are
available from our archive here:
