Line taken through centres x +50.5cm x -380cm [[image]] y -10.0cm y +57 X is the distance (horizontal from asteroid to edge of plate. y is vertical dist. to intersection of line of direction with edge. x/y = tan theta = 5.050 x/y = -6.667 theta = Position angle theta = 281.2 degrees theta = 278.5 x/y = tan theta Mean theta = 279.8 degrees As the asteroid is retrograding, the angle is in the 4th quadrant. Plate A 4603 No trail. Images slightly elongated but too poor for measuring direction. Plate A 4608 x +84.5 y -17.0 x/y = tan theta = 4.971 theta = 281.4 degrees Plate A 4610 Images too poor to estimate direction.
