Heads up: The International Space Station will be visible to observers on the ground in the Bay Area Friday evening, according to the Ames Research, NASA's center in Silicon Valley.
"At 6:56p today (Friday), we'll have a 5min @Space_Station pass, #BayArea! It'll appear in the NW, peak at 68°ht & disappear in the SE," Ames tweeted Friday afternoon.
If you're not sure what those numbers mean, NASA has setup a handy "How do I Spot The Station?" web page that explains everything.
The International Space Station orbits about 200 miles above the earth at a speed of nearly 17,500 mph.
The station will appear as an incredibly bright star, but it will be moving like a plane without the flashing lights.
