4 coloured lights in triangle shape

It was approximately 11:30 AM, I was playing in the garden with my 1 yo. son.
 I noticed in the sky a very bright orange/red light high in the sky. It was +/- 5 times bigger than a star. It seamed to stay at the same place. A few second later I saw 3 other lights lined up with the first light, the second light had the same colour as the first one, the 2 others were green / blue. The first light did not move and the other 3 formed a triangle around the first light which was exactly at the middle. I found that very strange because the objects were exactly over my head and after they formed the triangle, they did not move at all during a couple of minutes. I decided to take a picture, so I ran into the house. I met my girlfriend in the stairs and told her what I saw, but she did not pay attention. I took my camera and ran on the balcony, the triangle had disappeared, but one of the orange / red light was still there. It started to move forward at speed of a jet (I guess), I took a picture and saw it go away during many seconds until it disappeared in the clouds.
On the picture I took, we can only see a very small point in the middle of the sky. I was quite disappointed.
I was very surprised to read similar UFO reports on this site. At my opinion, that was no helicopters or planes, because the lights were very intensive, there was no engine sounds. Satelites wouldn't have been so bright in the noon sky. It looked so unusual and fascinating !
Witness provides interesting graphic of is sighting, which we may post.  PD
