I just saw a way-cool pass of STS with HST trailing (25 Dec, 18:13 MST). My wife spotted it first, slightly ahead of where I was expecting it. When I looked through my binoculars, I initially thought I was seeing a comet. STS was trailing a plume of luminous gas curving behind and below its trajectory. The plume was "comma shaped". HST was trailing just behind the plume of gas. Both objects were fairly low to the horizon (from here in Colorado Springs). I assume that the plume was gas venting from a maneuver burn. Anybody know for sure? By far, the most visually interesting satellite pass I have ever seen!
