Quote from the article:
“The Akron-Canton Satellite Tracking Group has
reported an unidentified object which was following the Vanguard ‘weather’
satellite in its orbit of the earth. Members of the group emphasized that it
could not be the rocket booster, which had been sighted earlier. They said they
had no explanation for the strange object.”
