    Re: Video of Davis MK 3 Practice at Sea

    It is a little difficult to find course, speed, assumed position, and then make sense of working notes which may be for a different day. What I am getting is an assumed position of 22° 6.2' N  76° 11.9' W at UT 17:30:00 off the GPS. The example observation made by the crew member (perhaps his first ever) has Hs 84° 10' lower limb Sun marked at UT 16:45:20. Course is 239° true? speed 6kts. The date is in question but seems to be 7/13/2019. LOP plots ok. Well done crew member! An index error of 5' on the arc was used on the working notes but not labelled. Semi diameter,refraction, and dip aren't labelled either. I am also wondering how he was able to keep from burning his eye some when bringing down the Sun since the mark 3 doesn't have horizon mirror shades :0
