Confirmed current Phobos-Soil track and time: [09 Nov 2011 UTC:] Prediction from pre-launch TLE: 9h:26m:48s 710 315.46ø 17.08ø Lit -16.4ø 19.569913810 28.010486185 PG Actual observed: 09:24:35 315deg19' 17deg01' (next to star Beta1 Cyg) Visual track exactly as expected, however 2min13s early. (More detail (lat/long etc) available on request.) The object changed brightness a number of times, from invisible to about mag 1 at times. Not sure if that would be the fairing or some other part- but only saw one object.
