If I understand correctly, satellite is directly between sun and earth (at lagrange point L1?), and somewhere at the time of the shooting there was an solar eclipse seen somewhere in Australia
Edit: nevermind, "The satellite is orbiting the Sun-Earth L1 point in a six-month period, with a spacecraft-Earth-Sun angle varying from 4 to 15 degrees", so it's not directly between.
- creshal 10y agoYes, it's at the L1 point: https://upload.wikimedia.org/wikipedia/commons/a/a5/Lagrange_points_simple.svg https://upload.wikimedia.org/wikipedia/commons/a/a5/Lagrange... No idea about the eclipse, though. There is none listed in NASA's eclipse portal for July: http://eclipse.gsfc.nasa.gov/OH/OH2016.html http://eclipse.gsfc.nasa.gov/OH/OH2016.html
- logfromblammo 10y agoObjects at Lagrange points L1 (between), L2 (small-body side), and L3 (large-body side), either have to continually spend propellant to keep station or use a Lissajous halo orbit around the point. In space, the choice to use more fuel or less fuel requires little consideration. So this satellite essentially scribes an elliptical ring around the sun as viewed from Earth. If the Moon passed between the satellite and the Earth, the Moon would appear from Earth to be 4-15 degrees away from the Sun, which would just be an ordinary new moon, not an eclipsing new moon.
