ISS passes over Berlin
The globe opens centered on Berlin (52.5° N, 13.4° E) with the ISS in gold and the city's place card unfolded to the station's passes over the next three days, worked out in your browser from the latest CelesTrak elements with SGP4, the same orbit the globe flies it on.
Each row of the Berlin list is one pass: the day, when the ISS rises above Berlin's horizon and sets again on Berlin's own clock (Europe/Berlin), how many degrees up it climbs, and from which direction to which it crosses. The rows in gold are the passes Berlin can see with the eye, the station sunlit against a dark sky.
The gold ring around Berlin marks where the ISS has to be for it to stand 10° or more above Berlin's horizon, about 1,400 km (870 miles) out; the dashed one, about 2,260 km (1,400 miles) out, where it first clears the horizon at all. Each time the station's track crosses the solid ring is one of the passes in Berlin's list.
How to read it
At 52.5° north, Berlin is a little beyond the farthest north the ISS goes, so it never passes exactly overhead; but the ground track comes within about 100 km of the city, and the best passes climb past 75° in Berlin’s southern sky. Because the station is turning around at these latitudes, Berlin sees bursts of passes on consecutive orbits.
Berlin’s summer nights stay pale for weeks around the June solstice, and the ISS can be seen there on pass after pass through the short night. The city’s two public observatories, the Archenhold in Treptower Park and the Wilhelm Foerster on the Insulaner hill in Schöneberg, are good places to watch with company and a clear view.
Questions
Why does the ISS never go straight over Berlin?
The station’s orbit is inclined 51.6°, so its ground track never reaches farther north than that, and Berlin is at 52.5°. The highest passes still come within about 15° of the zenith, high enough to look almost overhead from Berlin.
Which way should I look from Berlin?
South, mostly. Every pass over Berlin peaks in the southern half of the sky, rising somewhere in the west and setting in the east. The rows give the exact directions, and the gold ones are the passes Berliners can see with the naked eye.
Is Berlin’s winter too cloudy to see the ISS?
Berlin’s winter skies are often overcast for days, but cold, clear spells come with high pressure, and those nights are ideal: the station shows up crisp and bright soon after the early sunset. Turn on clouds with C to check the latest picture over Berlin.
