Subject: [NavList 5299] Exercise #10 Star Fix

Exercise #10 Star Fix

On 7 May 2008 a ship is steaming due South (180T) at 14.2 knots.  At

startime, a round of stars and the moon was shot.  The 1900 DR (ZD-10)

is 14 deg 11’N and Longitude is 145 deg 22’E.  Temp/Pressure is 83 F/

1010mb, Height of Eye is 106 ft, IE is 0.8’ off the arc.  The

following data was collected (Times in UTC):

Arcturus @ 08h 51m 13s Hs is 23 deg 10.4’

Spica @ 08h 52m 51s Hs is 28 deg 05.4’

Sirius @ 08h 55m 00s Hs is 37 deg 27.2’

Moon (LL) @ 08h 56m 52s Hs 19 deg  56.2’

Capella @ 08h 58m 32s  Hs 26 deg 49.2’

Determine the 1900 ZT Running Star fix.  (Most probable position).
