2009-05-20 - New Brighton, MN - Rectangle

At dusk, watching the first stars of the evening make their appearance a bright rectangle appeared at arround 90 degrees ( almost straight overhead). The Square looked something like being in the dark and looking at an unlit house, suddenly the door opens and there is a bright rectangle, 4 seconds later the door closes and...nothing..this is what it looked like, except the rectangle changed it apparent angle, as if reflecting sunlight. The sight then looked like a luminous square with a dark square within it.

WHAT MAKE THIS SO STRANGE IS THAT IT JUST DISSAPEARED... NO TRACE..NO VAPOR TRAIL..JUST EMPTY BACKROUND SPACE.

Being a star gaiser my whole life , taking astronomy class, buying telescopes and reading space related advances..this was like nothing I have ever witnessed.

No, this was not a meteor, balloon, or sattelite changing the angle and reflecting sunlite.

The apparent diameter was almost a quarter the size of a full moon.

The question is HOW CAN AN OBJECT APPEAR, CHANGE ANGLE AND DISSAPEAR..ALMOST AS IF IT WAS IN BETWEEN SOME SORT OF SHIELD...UNFORTUNATELY , THIS SEEMS IT WAS FOR MY EYES ONLY...VERY PECULIAR..
