Earthlings of Houston, tonight (Sunday) at 11 minutes before 9, there’s a 7 minute ISS flyover viewing opportunity. A must-see.

Conditions appear favorable for a clear sky, so the flyover this evening should be spectacular. If you've watched it before, you know. If you have not, you really should set a reminder and go watch it.

It'll be appearing in the west-southwest sky and will track across, going nearly directly overhead, until it disappears in the northeast sky. 8:48:34 PM is the exact time it will first catch the sun. ISS Detector says 6 minutes, 34 seconds of visibility, although Spot the Station says 7 minutes.

You can get an idea of how it'll look via Google Street View if you use this web site and let it have your location.

Keep in mind that there are HUMANS on that space station, and they're moving along at FIVE MILES a SECOND, which adds up to 17,500 miles per hour.

There's a "stationary bike" up there and the astronauts that ride it are going faster than any cyclist on earth could ever dream of.

The ISS looks like a jet or bright star, only when you lock your eyes on it, it's much brighter and then you see… it is much FASTER than any jet or anything else you'll see in the sky.

A fun thing to do is to call someone across town and have them watch it at the same time, with you on the phone. Get grandma and the kids outside with you. It'll blow everyone's mind.

Bear in mind, this isn't something that happens nightly, weekly, or even monthly. For the ISS to be visible, it has to be flying over precisely when it can be lit up by the sun, but while it's pretty dark on earth – ie: just before sunrise or just after sunset.

So it only happens periodically that it'll fly over where we can watch it, and the viewing opportunities are always less than 9 minutes long because of the way everything works.

You can get notifications of upcoming viewing opportunities by signing up on Spot The Station.

There are also some cool smart phone apps to help you see where to watch. One is the ISS Detector. Android link. Link for IOS. Get it & check it out! It's free.

Again, if you have not seen this before, I assure you, you'll find it worth the time you invest in it.

Enjoy, and… you're welcome.
