I observed it this evening under far from ideal circumstances: at an elevation of only 30-35 degrees, and seen through a hole in flying cloud cover, it crossed Aquila around 17:59:30 UTC just before it went into eclipse. It was very fast, at a steady magnitude +1.5.
Standing with my back pressed against the northern wall of the compound, looking south over the courtyard, I could see it grazing the roof of my house. Below is the photograph I obtained: maybe not quite spectacular, but I am glad I catched it at all. The start of the trail coincides with it clearing the roof edge! The image yielded 2 positions, with similar delta T (about +1.7s with regard to elsets then available).
Of course, a few minutes after this pass it was completely clear...
Yesterday evening I had dinner with Frans Rietmeijer, one of the Stardust scientists and an authority on IDP's. He is a personal friend and was in Holland for a.o. a Workshop. Over an Indonesian-Dutch "Rice table" he told me some interesting things about the preliminary mission results.
