The images are in .gif format and shown at a contrast intended to aid in their usefulness as finding charts (ie, only the brightest stars are shown). The center of the cross-hairs indicates the position of the event. Up is north, left is west. The size is 110 x 110 arcseconds.
WARNING: Since these images were taken during PLANET observations while the event was in progress, the source star is amplified over its baseline brightness.
