I have stretched the image for Stanton Bridge to get a vertical view. The circles were measured, indicating an order of size and  assigned planetary names based on planetary size. An alternative pint of view was done using proximity to sun with largest being closest. The circle outside the formation is slightly smaller than the 6th circle. I will leave it to the astronomy buffs to determine dates based on these

alignments. (see next three images in sequence)
