Georgetown, with the clock frozen at Tue 6 Oct 2026, 12:00 GYT and the ISS orbit CelesTrak published with epoch 6 Oct 2026, 00:20 UTC (TLE line 1: 1 25544U 98067A 26279.01444283 .00005131 00000+0 10208-3 0 9995). The next pass worth going out for is Fri 9 Oct 04:54 GYT, peaking 29.4° up in the ESE, mag -0.2, 8 minutes long; the best upcoming is Sun 11 Oct 04:56 GYT at 39.5° in the NW. Of 25 crossings in the week, 12 are in daylight and 5 can be spotted.

  1. 0:00 The ISS Pass Predictor finds when the space station crosses your sky, and which crossings you can actually see.
  2. 0:04 It works from the station's orbit elements. This recording uses CelesTrak's set from 6 Oct 2026, 00:20 UTC, with the clock frozen at noon that day in Georgetown.
  3. 0:10 The next pass worth going out for is Fri 9 Oct 04:54 GYT: 29.4° up in the ESE at mag -0.2, 8 minutes from horizon to horizon.
  4. 0:18 The best this week is Sun 11 Oct 04:56 GYT, 39.5° up in the NW.
  5. 0:24 In the next 7 days the station crosses 25 times, but 12 crossings are in daylight and only 5 can be spotted. The first, Tue 6 Oct 17:12 GYT, is marked Daylight.
  6. 0:32 Tick Spottable only and the list keeps the passes you can see, starting with Tue 6 Oct 18:49 GYT, 7.2° up.
  7. 0:39 Show path & sky draws where to look: the pass climbs from the SSW to its peak in the ESE.
  8. 0:46 Orbits drift: the tool reloads the orbit each visit, so check again on the day.
