      I have uploaded an image of Comet LINEAR 1999/S4 to the File section
      of ccd-newastro:

      newastro/CCD+Gallery/Linear_S4_July_6.jpg

      The image is a composite of seven separate one-minute images. The
      individual images were calibrated, aligned on the comet's nucleus,
      and summed in Maxim/DL.

      The image shows some nice detail in the vicinity of the nucleus.
      There appears to be a leading bulb of ions or dust, as well as a
      pronounced "shockwave" of denser dust streaming out from the nucleus.
      The tail is shown to be denser (or at least brighter) on the south
      side (left side of the image).

      The comet is moving fairly quickly, as you can see from the distance
      between the star images -- the images are little more than a minute
      apart in most cases.
