images of mystery object

Hi everyone,
outside scanning the sky on 29 may 07,caught sight of flickering light at an elevation of about 75 degrees.had my canon 400d dslr with 200mm telephoto lens ready,and shot about 50 frames.the object continued to flicker erratically in the viewfinder,and seemed self-luminous.the images are crops of the original raw images.
