At 5:43am on August 28th, 2020, the International Space Station made an appearance on the webcam, passing to the west of the Stawamus Chief before sunrise on a clear morning.
The International Space Station is visible as a bright star-like object between the two black lines that have been overlaid on the video, moving slowly up and to the left as the video progresses.
Visible International Space Station passes are relatively common, and NASA's own site, as well as several others, can be used to determine when a visible pass will take place. However, the webcam looks at a very small area of sky, and passes are only easily visible when the Sun is below the horizon at ground level, but the high altitude of the Space Station means it is still lit by the Sun, causing it to appear like a bright star in the sky.
Additionally, the weather has been extremely uncooperative when trying to capture an ISS pass, with several otherwise-excellent potential opportunities spoiled by total cloud cover. To date, this is the clearest pass of the ISS that the webcam has managed to capture. If a better pass occurs in the future, the site will be updated.
The complete timelapse video for August 28th, 2020 provides an overview of the day, although at the speed of the timelapse, the ISS is blur streaking across the sky for a fraction of a second.
