I don't think Guide is wrong. Because of the comet angle to the Sun, I
would suggest the image could be showing the ion tale. This tail resides
at a different angle and could be a possibility based on the present
comet position. I checked an image from 11 Dec 06 and two tails are
visible with the largest reverse from Guide but positions and angle to
the Sun are correct. I strongly believe we are looking at the ion
portion of the tail but that is an assumption at this point.
