The International Space Station is the brightest object in the night sky, save for the moon. It is easy to spot during one of its regular cycles over say Vancouver (and, by extension, much of BC and WA).
Tonight there will be a Class A+ (high angle, long duration) pass of the #ISS over Vancouver. 11:03 PM, Visible: 6 min, Max Height: 87°, Appears: 10° above WSW, Disappears: 11° above ENE. Go outside at 11:03 pm, look to the west and up and you'll spot it. It will be a bright light, not blinking in any way. It will become brighter as it moves closer to the zenith and then become very bright shortly after the zenith as the solar panels reflect maximum light down to earth.
The ISS will be ca. 400 km up and moving at a near-constant speed of 27,000 km/h.
Basically it will be right over head at 11:06 pm. Chart courtesy of heavens-above.com.
Well, no chart. I'm not sure how to load an image into these posts.
