big hit

The BGO director dove into the individual frames of the M81 imaging run (hmmm) and found an unusual circumstance on one of the shots.

3D plot of direct cosmic hit

The 3D plot shows the profile of my bright point (the kinda tall peak) and the nearby star (the little mound). He remarked, "It was a helluva a cosmic 'whack!'" Indeed. I guess the cosmic ray came in perpendicular. It saturated the CCD suggesting a direct hit versus a graze.
