90. On 12 December your 1830 ZT DR position is LAT 24°16.0' S, LONG 41°18.0' W. You are on course 235°T at a speed of 16.0 knots. You observed 3 celestial bodies. Determine the latitude and longitude of your 1930 running fix. Body Zone Time GHA Observed Declination Altitude Rigel 1845 329°19.7' 19°54.7'' S 8°13.4' Peacock 1910 107°58.4' 32°43.9'' S 56°47.8' Markab 1930 73°04.1' 39°53.1' N 15°06.5'
The 1930 running fix is determined by advancing earlier lines of position (LOPs) to 1930 along the vessel's dead-reckoning track and intersecting them with the Markab LOP taken at 1930, resulting in a position of LAT 2416.9'S, LONG 4118.2'W.
