Stationary silver ball very high in daytime May 1980 observed approximately 45 minutes.

One clear  day in May 1980 I saw a stationary silver ball so high in the sky as to be practically invisible. I found it totally by accident while on a lunch break in a park called `Sugarhouse Park`. I was lying on my back gazing at the contrails in the otherwise clear sky. I spotted it and couldn`t believe what I was seeing. I lie there 45 minutes or so before I had to go and tell somebody and of course I could not find it again. Later on TV news was reported two similar sightings. One in Brazil, and one in Australia. The one in Brazil was moving at a high rate of speed at tree-top level with no sound and lasted about 90 seconds. The Australian sighting was out over the ocean off of a beach. It was stationary and was video taped until dark. The next morning it was gone. This all happened in a time of about two days.Absolute truth.
Date is approximate.  PD
