If it’s clear enough, and if I’ve read the magnitudes and times and directions correctly on Heavens Above, here’s what I’ll be doing that night:
- At 5:00pm I’ll go outside and stand in a nice dark spot. (I live in the middle of San Diego, so that takes a few minutes to find.)
- At 5:05 I’ll look to the northwest for a bright object moving toward the northeast. If it’s moving slowly and not blinking, it’s the International Space Station. Population: 6. I’ll wave to Daniel, Anton, Anatoli, Oleg, Donald, and André.
- At 5:07, when the ISS is as far up as it’ll get in the northeastern sky, I’ll look to the southwest for a dimmer object moving toward the northeast. If it’s moving slowly and not blinking, it’s Tiangong 1, the first part of China’s space station. Population: 0 so far.
- Until about 5:10, when Tiangong 1 is right overhead and ISS drops below the eastern horizon, I’ll watch the two of them share the sky.
