I’d love to hear about your stargazing experiences. Be sure to let me know how your spotting goes! Check out the sighting data for the ISS on November 12th in my city: The ISS will become visible at 6:15 AM for 4 minutes. Because of the curvature of the Earth, satellites are still lit by the Sun after the Sun has set in a particular location, especially at this time of year in the northern hemisphere. If it's a star, then it would follow all the other stars in the sky and rise and set. Asked by Wiki User.  Use a compass to determine the direction to look. Sunlight reflecting of it. At first I thought it was a bright star, or perhaps the headlights of an airplane, but it wasn’t. Top Answer. At first glance, they appear to be stars, but given a closer look, they are clearly colored red, white, and green - all three colors on every single one of them - and they appear brighter and bigger than stars. usually airplanes have a sort of repeating pattern with their marking lights, even a few colors as well, greens blues reds whites, etc. You bet! 0 1 0. Settings I used were: ISO 200, f6.3, 1/320 sec. Sattelites don't have any blinking lights, at least ones that can be visible from the ground. The satellite's metallic surfaces act as mirrors for the sun (specular reflection). My 10 year-old was ecstatic when he learned that some of them could be spy satellites. With a little coaching (“No, that one’s an airplane”) the kids quickly became expert spotters. You can tell a satellite and an airplane apart because (1) airplane navigation lights often have a strong (red) color, and satellites often do not, (2) a satellite looks like just a point of light even through binoculars, while for even a small airplane at 10 km distance details (such as navigation lights on both wings) can easily be seen through binoculars, (3) a satellite … It’s pretty cool…. Usually, the satellite's orientation is steady, only slowly moving. It will appear in the west-northwest sky at an elevation of 25° and disappear in the north-northeast at an elevation of 10°.
