15 circular yellow lights ,in the form of triangle head moved from east to north west for 2-3 minutes befor disapearing in the horizon.I was looking at Polaris (north star) from my balconey to align my telescope when I saw in my naked eyes a group of small,yellow circular lights in the form of triangle head(around 15 of them) passing above me in the sky at a coniderable speed going north-west direction, I called my wife to see them and she did and then I called my 4 dauthers to come with us to the roof to have better view and tracking and they kept traveling as a group but some of them where not keeping the same distance and speed from each others (as if they where slowing and speeding up) , this is not satelight pattern ,nor it could be aircraft pattern ( no sound at all) and they where very high up in the skey ,this lasted 2-3 minutes and then they disapeared in the horizon the was full of haze and city light. This is the first time in my life I see an UFO.
