Coincidentally spotted the #ISS last night from our roof top. Light from the setting sun in the west illuminated an object moving eastwards across the clear sky at rather incredible speed. At first it looked like a very fast airplane but it had no blinking lights, it was just a single spot of light. A friend noted the current time (18:44) when it had moved past Jupiter which could also be seen, and later looked up the object in #stellarium and confirmed that what we saw was indeed the ISS 😀 🛰 ✨

@oa wow great! What puzzles me though: the ISS did in reality pass significantly "below" Jupiter when we looked at it, like quite a few arc degrees at least. Yet all the charts show ISS passing *exactly* over Jupiter. Where does the discrepancy come from? Ground elevation of Berlin??

@neeels Hum. Not *exactly* over. If you zoom in (you can click on the map and adjust the map size to 1600). I think it's a scale problem.

@neeels … Something like that. On the scale of the sky, the distance must have been much more impressive.

@oa what we saw was more like here, quite far off:

@oa hmm, has the ground elevation in, so either that wasn't Jupiter (am pretty sure it was) or maybe the actual altitude of the is not part of the data set? It does fall irregularly and gets boosted further up every now and then. Though at least heavens-above seems to account for altitude: heavens-above.com/IssHeight.as and one km shouldn't make such a large difference
