Thus, the observation mode for GEO objects is based on a dawn-dusk sun-synchronous orbit satellite.
A low earth orbit (LEO) satellite, especially a dawn-dusk sun-synchronous orbit satellite, is useful for space-based observation.
More people each day at dawn and dusk, under sun, rain and moon, and the Stranger singing his song to the sea.
Come dusk, the sun beds and V.I.P. tents along the docks are replaced by elegantly set white tables and twinkling candles, as the beach clubs morph into top dinner spots and cocktail lounges.

ST5 deployed into a 300 × 4500 km, dawn-dusk, and sun-synchronous polar orbit (period: 136 minutes) with 105.6° inclination angle (Slavin et al., 2008).
Because the date and time for the game were moved back this year to serve the needs of the B.C.S. and its television agenda, the game did not begin in the sunshine and conclude in the dusk, with the sun setting in the Arroyo Seco by the San Gabriel Mountains, traditionally one of the most gorgeous scenes in all of sports.
At dusk, the setting sun gives the Sangre de Cristo Mountains — Spanish for "Blood of Christ" — an ethereally red hue.
And for a few minutes after dawn and before dusk, when the sun's rays are at their reddest, most visitors see (unless, like my sister-in-law, you get two days of torrential rain) a truly awe-inspiring spectacle.
When Spider-Man perches atop the Empire State Building at dusk, the setting sun flares off countless windows as a thousand street lamps below flicker on.
