The selenographic coordinates were computed using the images by Lena and Sposetti  displaying several lunar features that were of very low contrast on the dark limb of the imaged lunar

surface. 

After alignment with the edge of the lunar disk, computation of the libration, and overlay of the rotated Moon's surface matching the image, a coordinate map was superimposed on the flash image. This procedure was performed using the LTVT and VMA software packages. The impact occurred near the crater Seneca C (coordinates of the flash correspond to 73° ± 4° E and 27° ± 3° N).
