On 26 November your 0535 DR position is LAT 27°18.9' S, LONG 30°18.4' E. You observe an unidentified planet bearing 037°T at an observed altitude (Ho) of 50°06.4'. The chronometer reads 03h 33m 16s and is 01m 48s slow. What planet did you observe?

Question

On 26 November your 0535 DR position is LAT 27&deg;18.9' S, LONG 30&deg;18.4' E. You observe an unidentified planet bearing 037&deg;T at an observed altitude (Ho) of 50&deg;06.4'. The chronometer reads 03h 33m 16s and is 01m 48s slow. What planet did you observe?

Accepted Answer

Option D: Mars. Planet identification compares calculated intercept parameters (GHA and declination from Nautical Almanac) against observed altitude and azimuth. Matching coordinates at the given GMT positively identifies Mars.
