From 17:38 to 17:43 GMT+0100 (i.e. 17:38 to 17:43 local time here in Austria), ISS can be seen on the (currently totally cloud-free) sky.
salzburg.orf.at reports this. For a map where the ISS will exactly pass, have a look
here (or at the map on the left side). Ah, for those interesting in seeing ISS, it will enter the sky at about west-northwest, which is at about 67.5 ° on compasses with counter-clockwise angular spacing (like mine
or 292.5 ° on compasses with clockwise angular spacing (don't ask me, I have absolutely no idea why my compass is counter-clockwise. At least the compass needle points to north
.
It was about 1.5 years ago when I last saw ISS. At this time, a rendevouz between the ISS and a space shuttle was planned, and could have been observed, if the space shuttle mission hadn't been cancelled due to bad weather in Florida.
Anyway, even without the space shuttle trying to dock onto ISS, it was great to view.
Martin Piskernig suggests that a lot of
UFO sightings will be reported by uninformed people (of course, for them, the ISS will be an UFO, since they are simply unable to identify it). Let's see whether there will be TV reports about it.
Update: the ISS was nice to see, really bright, much brighter than the last time I saw it. And it disappeared at exactly 17:43, as predicted. So, the visibility definitely has something to do with the angle the sun light is reflected to the earth.
