Not well seen in mediocre and variable conditions, possibly due to aircraft vapour trails. This is a very narrow oval 5:1 or 6:1, with the major axis aligned SSE-NNW. The halo appears mottled but no structure was detected. The S end of the halo is wider than the N. The brighter central region is also oval.
