    Re: Latitude and longitude by birdfoot

    Another nice puzzle!

    The photograph shows Orion rising feet first and so is taken in the southern hemisphere. The figure of Orion lies on the the celestial equator and runs and roughly north-south in the sky centred on R.A. of 5h 30m. Since he is seen here lying nearly on his side this can't be a long way below the equator.

    From the timestamp 2016/08/18 8:32:21 UT we know that Greenwich Sidereal Time (GST) is 6:19:00. The fisheye distortion makes things a bit difficult but a rough estimate might be that Orion rose an hour and a half ago . That would make the Local Sidereal Time (LST) around 1:00 and which makes the longitude LST-GST roughly 80°W.

    The observatoty buildings that can be seen in the photograph suggest that this was probably taken from La Silla, Chile at 29°S 71°W
