Astronomy Fact
When you look at the Andromeda galaxy (which is 2.3 million light years away), the light you are seeing took 2.3 million years to reach you. Thus you are seeing the galaxy as it was 2.3 million years ago.

Earth Satellite Vehicle Passes
Notes about viewing ESVs:
When using lookangles, choose passes with high magnitudes; less than 6.0. ("Looks" are local time.)
Best viewing is when ESV is in Earth's penumbra; on map-solid line during night.
Dotted line on map denotes ESV is dark, in Earth's umbra (shadow).
Objects in orbit have to maintain a speed of at least 17,500mph, therefore ESVs traverse the sky noticeably different than aircraft.
ESVs appearing to blink are either tumbling rocket bodies, or spinning payloads with deployed solar arrays.
High-Eccentricity objects have a more ellongated orbit. Ground trace looks like a backwards C.
Regression-Ground traces will move West with each orbit due to Earth's rotation.
