Saturn at East Quadrature – 2018

   Tuesday September 25th the position of the planet Saturn with respect to the Earth and the Sun places this ringed planet at what is called eastern quadrature. Saturn is at a 90 degree angle from us as this graphic shows. Think first quarter Moon as that is a fair comparison of the relative positions. At this position Saturn follows the Sun across the sky from east to west as the Earth is rotating, meaning that Saturn rises after the Sun and sets after the Sun.

   Where is Saturn now? Saturn is over the southern to southwestern horizon at sunset and is east (to the left) from the reddish star Antares in the constellation Scorpius the Scorpion. Further toward the west is the planet Jupiter, and to the east from Saturn is the planet Mars. And the 16-day old waning gibbous is above the eastern horizon.


   Saturn currently has a 0.47 apparent magnitude and is centered on the Milky Way within about 2o from a few easy to see Messier Objects. These include M-21 a 7th magnitude open star cluster; 5th magnitude M-8, the Lagoon Nebula; and 5th magnitude M-20, the Trifid Nebula.

   This is a short 5 minute video I made as part of a live musical performance called “Orbit” that I was part of in May 2011. This is a piece from the much longer tour of the solar system performance and video and shows Saturn and some of its moons as viewed from the Cassini spacecraft that month.
