Somewhere over your head the future is happening, part II

How to tell the difference between the International Space Station and all the other air traffic overhead:

• The ISS might be visible immediately on the horizon, or it might wink into existence depending on the geometry between you and the sunlight reflecting off the solar panels.
• Airplanes have green and red navigation lights and may have flashing strobes.
• The ISS will suddenly fade from view before it reaches the far horizon as it passes into the earth’s shadow.
• The ISS will be above any clouds (at least I really hope so!)

Tonight’s pass over Los Angeles just now was one of the best I’ve seen. Amazingly clear sky this evening. So far, it seems that Heavens Above has slightly more accurate pass timings than NASA.
