- Q109 - Navigation Problems: Oceans
196. On 2 October your 1845 DR position was LAT 28°09.2'S, LONG 167°48.1'E. You observe a faint star through a hole in the clouds at a sextant altitude (hs) of 20°45.6' T, bearing 201.5°T. The index error is 1.3' off the arc, and the height of eye is 42 feet. The chronometer reads 07h 46m 19s and is 00m 51s fast. What star did you observe?
Alpha Muscae's computed altitude and azimuth agree with the corrected sextant altitude and observed bearing, given the date, time, and DR position, making it the correct identification.
