Notes about viewing ESVs:
  • When using look angles, choose passes with high magnitudes - less than 6.0.
  • 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.
