Fine Scale Structure in Cometary Dust Tails - Figure 5.18 - Sunward aligned temporal maps of McNaught as seen by HI-1A with MGN enhancement

After a 6 hour data gap, on 22:01 UT on January 12th 2007, new near vertical combed features are visible which intersect older striae. Note that features on the far left of the temporal maps are artefacts from the overexposed region near the comet's nucleus.
