An evening ISS pass over Georgetown, Guyana, that fades out high in the sky: the station flies into Earth’s shadow, which reaches overhead once the Sun is about 20° down.
Shows Georgetown (6.80° N, 58.16° W), the ISS pass of Wed 4 Nov 2026 after 18:45 GYT, predicted from the CelesTrak TLE with epoch Mon 5 Oct 2026, 20:20 GYT (6 Oct 00:20 UTC).
A silent 30-second explainer drawn from the site’s own sky chart and ISS code. It shows one evening pass of the International Space Station over Georgetown, Guyana, that disappears partway across the sky, then the geometry that makes it disappear.
Wed 4 Nov 2026, Guyana time, predicted from the CelesTrak two-line elements with epoch Mon 5 Oct, 20:21 GYT: the station rises in the SW at 18:46:27, reaches 88° up in the NW at 18:51:51, enters Earth’s shadow at 18:51:56 while 84.3° up, and sets unseen in the NE at 18:57:15. At the moment it vanishes the Sun is 20.0° below Georgetown’s horizon.
Earth’s shadow is drawn as a cylinder, to scale. A station 422 km up, straight overhead, leaves sunlight once the Sun is 20.3° below the horizon (20.3° for 420 km). A prediction from elements a month old can be off by several minutes, or miss the pass altogether after a reboost, so check the ISS Pass Predictor for current passes.
0:00 Some ISS passes stop halfway: the bright dot fades out high in the sky. Here is one, and why.
0:03 Wed 4 Nov, from 18:46:27 GYT: the station rises in the SW, sunlit against a dark sky, as bright as magnitude -4.2 by the predictor’s estimate.
0:11 18:51:56: 84.3° up in the NNE it fades out. Nothing switched off: it flew into Earth’s shadow.
0:15 It keeps going, unseen, and sets in the NE at 18:57:15. Only sunlight on its panels made it shine.
0:18 Earth’s shadow climbs the sky after sunset. A station 422 km up overhead goes dark once the Sun is 20.3° below your horizon; here the Sun was 20.0° down.
0:26 Evening passes fade out; morning passes appear out of nowhere. The predictor labels them Eclipsed.
