    Celestial in the Gulf of Oman
    From: Frank Reed
    Date: 2014 Sep 8, 23:04 -0700

    Here are a few photos of an Indian navigator doing some celestial navigation, or at least going through the motions, aboard a traditional dhow in the Gulf of Oman close to 25° 24' N, 57° 31' E. These images are screen captures from a television program. A few puzzles to work out:

    • Is the navigator really navigating? Or is it staged, just for appearances?
    • What type of sextant is he using? Is it a real instrument? Does it have any flaws or faults?
    • Given that the photo was taken in mid-October, what is the time of day consistent with the apparent observation?

    Those questions can be answered by navigational science. Finally, one question requiring a little pop culture:

    • If the photo/video was taken by someone nicknamed 'Passepartout' and working for the BBC, what year was this photo taken? And what moderately famous person was also on board the dhow?
