RE : http://fer3.com/arc/m2.aspx/USCG-Sample-Problem-2-for-Southern-Hemisphere-Rudzinski-apr-2013-g23605

Good Day Greg,

You should be soon waking up ... therefore you need some reading ! :-)

At 10:00 LT, i.e. 20:00 UT, I find the following position :

S 09°41'8 W 152°43'7 with a LOP's dispersion of 0.1 NM (Excellent !)

This result - subject to crosscheck with Peter Hakel (see " http://fer3.com/arc/m2.aspx/Group-Project-USCG-student-sample-problems-Couëtte-apr-2013-g23607 " ) - seems within 1 NM from your result.

Best Regards

Kermit

PS : May I suggest that there should be one example with a Southern Declination CIRCUMPOLAR Star with a Local Time somewhere between 180° and 270° ? As I can recall from previous practice (many many moons ago) the heights interpolations from the HO tables require extra care under such situations. This would involve building up one other example ... if you think this idea is OK, I can build it up.
