198. On 19 November your 0200 zone time DR position is LAT 20°29.0' N, LONG 150°21.3' E. You are on course 136°T at a speed of 18 knots. You observed 3 celestial bodies. Determine the latitude and longitude of your 0600 running fix. Body Zone Time GHA Observed Declination Altitude Regulus 0530 198°24.3' 77°21.3' N 12°03.4' Arcturus 0532 137°03.2' 22°47.9' ' N 19°16.7 Suhail 0537 215°10.4' 26°44.9' S 43°21.2'
The correct running fix is determined by reducing celestial observations, plotting lines of position, and advancing them to a common time, resulting in a latitude of 1933.0' N and a longitude of 15110.0' E.
