Triangle shaped object with 3 red lights at each side.3 red lights with a triangle shape heading from the south west to north east in a direct straight line.the black shape of the object was visible to the background of stars. The sky was incredible clear.Lets say that we have a view of field of 180 degrees than the object was visible for 30-40 degrees. its difficult to quess how fast it went, but it travelled with almost 10 to 15 times its own size per second. and as i said in a straight direct line.the altitute is also difficult to say. but it was probaly higher than 3 km.there was absolutely no sound hearable.
