On Saturday, July 19th, the International Space Station will pass almost directly overhead starting in the southwestern sky at 10:12 PM.
The station will be observable as an extremely bright, fast-moving object, moving southwest to east-northeast. It will take about 5 minutes to cross the sky.
If you’ve never seen the ISS fly by, it’s worth standing outside on a summer’s night (hopefully cloudless – a lot more fun) and away from city lights to observe the satellite’s motion. It is quite unlike anything else in the sky, day or night. It will be brighter than Jupiter, currently the brightest object in the night sky (excepting the moon, of course).
Even if you aren’t the least curious about the technology of the multi-billion dollar space station, it puts on such a unique performance that it’s well worth hanging outside for a few minutes to watch it. Not to be missed. But if you do, here’s a place where you can find out just when it will pass overhead again.
