Thirty minutes ago I observed a bright transit by the USA 144 Titan rocket, reaching ~45 deg in the NNE at a range of 325 km. It was steady and close to the magnitude 0.0 of Vega at its brightest. It appeared slightly yellow in comparison to the blue-white of Vega though I suppose hat this could be due to the different spectral types of Vega and the Sun, rather than the intrinsic colour of the Titan. The observation (below) was earlier in the transit and shows it smack on time with Quicksat predictions from...
