The upcomming shuttle launch to ISS will be in early twilight. It will be in full daylighg while the sky is still fairly dark for those viewers along the US east coast where launches are sometimes visible. What sort of condensation can be expected in the plume? I would expect quite a lot, but the long range cameras near the cape never show any visible plume after SRB sep. This launch will have illumination geometry for some fairly good forward scattering so I'm hoping for a show worth dragging people out of bed for (early evening launches out of VAFB are often very impressive for viewers in the Southwest). I've never heard of such observations for a shuttle launch though, but I can't recall any that have had quite the right timing for this either.
