Mercury has been visible in the early morning twilight recently. Jupiter is on the opposite side of the Sun from our location. But, Earth is coming around in our orbit catching up to Jupiter. As a result, Jupiter is also a morning twilight object in the same vicinity as Mercury. They were to be very close to each other low in the eastern sky on 11 Oct 2016. Guess what. It was cloudy. But, I did go out on 10 Oct at 6:45 am when it was very clear to capture the view.
The first image is how it looked to my unaided eyes. The second image is zoomed into the center part of the first just above the tallest trees in the vicinity of a faint jet trail.
The evening on 9 Oct was also clear. An email notice told me about a bright reflection off of a communication satellite that was to pass right over my location. The satellites are part of the Iridium system consisting of 72 satellites in polar orbits that provide worldwide coverage for satellite phones. Their 3 antennae shown in the image below are flat and highly reflective of sunlight. The positions and angles of each antenna are known allowing predictions of those reflections across the surface of the Earth.
The email notice said the location in the sky was toward 148˚ in the southeast and 50˚elevation. It would last about 10 sec due to the 17,000 mph speed of the satellite.
The sky was dark. I set the camera using a protractor for elevation and Google Earth for direction over my neighbor’s house. I started recording a minute before the due time of 7:52 pm. Success. Here is the video trimmed for time to the actual event.
