    Don, you wrote:
    "Holy Cross Cemetery in North Arlington, NJ?"

    Yes! Or at least, very close to there (my "fix" is across the street right at the entrance to the soccer field). From the image alone, I believe the location can be pinned down to within about twenty feet north-south and maybe fifty feet east-west. Would you be interested in describing your methodology first? Or should I go first?


    I am sure my method was not nearly as analytical or precise as yours.

    First I just guessed Eagle Rock Reservation, near High Lawn Pavilion. This was simply knowledge from my youth growing up in the area, that this site had an excellent view of the New York skyline, being the first 'mountain' in from the coast, and it was a popular site for photos.

    Then I looked up the height of the radio antenna on the Empire State Building (about 200') and compared it to the diameter of the sun. A little math gave me a distance of about 45,000 feet to the viewing site. I opened Google Earth, and was disappointed to find that Eagle Rock was too far away.

    Next I looked up the azimuth of the rising sun, about 110 deg. I measured back 45000' along a 290 deg bearing, and looked for a likely open area nearby. Holy Cross Cemetery looked promising, and was the kind of place where someone might have easy access at dawn. I googled a few images that showed it had a clear line of sight to mid town Manhattan from rising ground.
