Just finished watching this duo on the same pass as Craig is likely to see. STS was about a minute ahead (not timed), magnitude -1, Mir was around magnitude 2.5. Rather faint. Observed both turning red as they entered the umbra (that is the Earth's shadow for those of you on the US west coast). Sunday morning there should be a whopper-monster flare from Iridium 6 near Polaris from my location. Ron Lee
