^aFlashes are named after dates. A flash observed on Nov. 7, 2016 (UT) is named “161107”
^bThe times of detections. They are accurate to a second
^cSelenographic latitudes and east longitudes in degree. They are accurate to a degree except for the longitudes of Flashes 170204d and 170501
^dThe number of frames where each flash is recognized by visual inspection
^eThere may be a frame that shows the flash if the frame drops had not occurred. See text
^fThe exposure time for a frame and the electrical gain of the camera
