So, this day, I smoking cigarettes outside. I'm used to do it looking at the stars. I have a certain knowledge of the normal position of the star and the planets and always look for venus or Orion's Belt, and normaly, I know before looking for it more or less where it should be.This particular night when I look first glance at the sky, I see venus out of ambitual site. When I try to look venus where it should be, he certainly was there. So it was not Venus. When a come back to see this object, I realize the object is moving, so a belief to be a satellite or the ISS.I keep track of the object and realize is not moving in linear and change the inicial NW to SW derection to W. When I start to trying figured out what it is, the object make a total stoppage and stay like a minute in the same spot. I began to feel afraid, because there is not anything that can go to that height suddenly stop . After that 1 min, stoped in the same spot, the object become brighter and disappear.Object it always the same size, and same bright of venus. Only in the end become brighter and orange like color before disappear. in addition to this, it's important mention the " serra da estrela" ( the most elevated place in mainland Portugal ) it's right behind me, and the object appear to come moving from there.I stay with the feeling that the object stopped and disappeared, somehow realize I was watching it. I am very sceptical, and a never share this with no one, but haunts me down not know what I see that night. ( sorry my lousy english)
