Astronomy Fact
The planet Venus does not tilt as it goes around the Sun, so consequently, it has no seasons.

Space Track-Satellite Passes

International Space Station View Look AnglesESV Ground Trace
Satellite Ground Trace courtesy: Heavens-Above.com
Bright Satellite List for your location.

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 the map, it's the 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.
