Round silent mirror white/green object flying low over the river heading towards the sea.

We, my father, a friend of his and I were on a fishing trip close to the mouth of the Unare river which ends at the Caribbean sea in the Anzoategui state in the center-north of Venezuela in South America.  We slept in hammocks tied to small trees with few leaves present. 
At around one in the morning, the little town close to where we were turned off the electric power.  So we were in the dark except for a bright moon up in the sky.  
Five minutes after the town went dark this object flew overhead heading north.  It was the size of VW bug, round, shiny white as a the most perfect brightest mirror you have ever seen.  
Around the white mirror there was a solid green light all around the object.  The object flew silently over the river heading towards the ocean. If I had a bow and arrow I could have hit it. The light was so bright that I could see everything around me almost like it was daylight, except that all was green.  I asked my father :"Did you see that?"  He said : "Yes."  My father's friend was asleep. 
A few days later I asked him about the object and he denied having seen it.
I wanted to be an astronomer when I was a kid so I am familiar with meteors and astronomical objects.  And this was nothing natural or man made.
The year I saw that object the song Total Eclipse of the night was been played a lot.
I am writing this for your information and you can use this anyway you want.  No need to contact me about it as  nothing else happened.
Witness indicates that the date of the incident is approximate.  PD
