Coincidentally spotted the 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 and confirmed that what we saw was indeed the ISS ๐Ÿ˜€ ๐Ÿ›ฐ โœจ

Correction: The time was around 20;44 (sun sets on Berlin around 9pm at this time of year).

Oh no no no wrong again, it was at 22:44 in fact ๐Ÿ™ƒ

@florian I *think* CEST, but better ask @neeels to make sure. I wouldn't trust my own judgement of the facts anymore at this point ๐Ÿ˜€

@stsp
Don't try to spot the ISS with @benno btw ๐Ÿ˜‹
@neeels

@florian why not, doesn't the ISS like benno?

@neeels private joke.
We we sitting with a bunch of people outside having a few beers. And Benno mentioned that the ISS should pass over us soon. So we are looking for it for half an our or so. Didn't show up.
A few ours later on our way home this bright spot passes over us: Hey Benno, what's that? Benno: Oh, some satellite.

Turns out it was the ISS he had looked up the timing in the wrong location ๐Ÿ˜€

@stsp Somewhere on the #NASA Website they have a timeplan for the #ISS . It's really cool if you know that they fly with 27.600 km speed through the orbit and need 93 min. for one earth rounding ;-)

@stsp it was 22:18 CEST and ISS in reality passing just under jupiter, though it actually mismatched slightly with what #stellarium showed, even though using location "Berlin Schoeneberg". c1.staticflickr.com/8/7403/973

@stsp I should install #Stellarium, too. I've been thinking about it for some time now, but it always got pushed back by other needs. Last time I remembered about it was when I saw it in the Featured section in #Fedora's package manager GUI. Suppose it's a sign. :)

@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 โ€ฆ 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, #stellarium has the ground elevation in, so either that wasn't Jupiter (am pretty sure it was) or maybe the actual altitude of the #ISS 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

@neeels Ah! Then you were in Neubrandenburg! Admit it! ๐Ÿ™ƒ

@oa my heart was in xberg, maybe my mind went off to Neubrandenburg?? ... I think I need to try and spot the #ISS again and see if i can reproduce le offset or identify my mistake (if not a huge conspiracy! ISS is leaking chemtrails in space to cause fake global warming so the freemasons can hide the aliens' ufo heat signatures and capitalism can continue to vaccinate us with sterility genes!!! So that's why they don't want us to know its REAL orbit! Is this true? It might? O_o')

@neeels Um, you're gonna have to wait a while before you see the ISS over Berlin again. Unless you get up in the middle of the night, it seems that it could be possible from July 19 (unless an alien intervention organized by the FBI in Area 51 forces NASA to change all its plans of course).

@oa since I'm usually awake in the middle of the night anyway I think I can take a break from hacking and have a tea up on the roof. Shouldn't #ISS stay in the same orbit and pass by me every 90 minutes or so on the same trajectory? I thought I should see it near every sunset?

@neeels The ISS will cross Berlin's longitude every hour and a half. But will pass over berlin during the day and under the horizon during the night. It will be necessary to wait for everything to shift gradually so that the ISS has higher passages and synchronized with our nights.

@oa ZDF.de currently showing a documentary about Alexander Geerst's trip to the #iss *right now*, also including images of the orbit. Now it all makes sense. zdf.de/dokumentation/terra-x/d
