Satellite Spotting & Operations Handbook
Copyright @ Satellite Spotting. All rights reserved.
You may have already noticed satellites passing overhead without realising what is being witnessed. On any clear starry night (moonless if possible) wait patiently for a moving star like object. They should be travelling silently and in a straight line or in a perfectly gentle curve across the sky. They may even fade from view over a few seconds. These are the satellites.
I have recorded a few examples to give an idea of their speed and majestic movement via an instrument called an 'Image Intensifier.' Full recording details are given in the book.
