| A sequence of nine consecutive images recorded by the Halley all-sky imager on day 134, 1994. Auroral emissions in the form of an omega band are seen to move westwards over Halley during this period; the shape of this structure is most clearly seen during the time of closest approach in the images at 05:15, 05:20 and 05:25 UT. |   |
