This image shows well Panstarrs' extraordinary spike, which is now six degrees long, although only two degrees is shown on this image. We cross through the orbital plane of this dusty comet on May 27th so the dust is seen edge on, hence the spike.... The small plume on the rhs is the normal dust tail, i.e. the dust blown away from the comet and so roughly in the anti-Sun direction. The spike is debris along the orbital plane. Martin says he can't say he recalls ever seeing an orbital plane spike or 'anti-tail' quite like this before. This comet is all dust and more dust!! The image was taken from itelescope.net's New Mexico base with a Takahashi FSQ 106 and SBIG STL11000M.... LRGB exposure of 300:60:60:60 secs.....
