About this image

Time stated is UT.

This is a pseudo-colour representation of the FITS image. I conservatively estimate the coma diameter at 5.6 arcmin. Nick James' most recent estimate of the coma diameter - at 6.2 arcmin - can probably be attributed to the better sensitivity of his equipment. The ion tail is pointing at PA 300deg, which (reassuringly) is in the anti-solar direction.
