【International Space Station with Naked Eye View in Xining Area Tonight】
【Tonight the Xining area can <不需要任何工具>directly see the International Space Station (Sputnik) with the naked eye!! Tell the people around you】
Tonight between 19:57:28 and 19:58:35, if the weather is clear and cloudless, then you can look up at the night sky during this time, wait a few minutes, and you will see the international space station moving in the night sky [its brightest at 19:58, the night sky position is: North], the International Space Station looks like a bright star in the night sky moving slowly (directly to the naked eye, no telescope required). Surely you've ever found a star moving slowly in the night sky before, not like an airplane, not like a luminous kite, so the first thing that comes to your mind must be a UFO (UFO)?! Remember that this is our human Artificial Satellite International Space Station, orbiting the Earth at a height above our heads [apogee altitude: 422 km + perigee altitude: 413 km].
The time and location of the International Space Station are different from place to place, but the nearby areas do not vary much, so you can refer to it.
Details of the time forecast for your location can be found using riverons-above.
【Note: When watching, please pay attention to safety and warmth】
Go and tell the people around you to watch it together! Tell him or her it's the Sputnik International Space Station, and you might be tall in an instant!
Figure 1: A map of the sky area forecast for the Xining area tonight (January 31), arrows and solid lines, you can see the direction of the satellite in the night sky position.
Figure 2: A map of the trajectory of the substellar points predicted for the Xining area tonight (January 31), with a highlighted circular area indicating a range of at least 10 degrees of the satellite's horizon altitude. The size of this circular area depends on the height of the satellite. Roughly speaking, the satellite can theoretically be viewed from high-lit circular areas.
