I have used the wrong date to calculate selected stars for Titanic's last celestial fix . The correct date is 4/14/1912 and not 4/15/1912. See attached USNO pic 98 and 100 for correct data. The hypothetical 3 and 4 body plots are still good from the previous post.

Paul,

Working in round numbers I get:

Early twilight starting at UT 2230 4/15/1912 ZD +3 Lat. 42* N Lon. 47* 30' W (Sun Hc -8*)
GHA Aries 181* 12'
LHA Aries 134* for A.P. Lat 42* N Lon. 47* 12' W
LHA Aries 133* for A.P. Lat 42* N Lon. 48* 12' W

Pub 249 recommended selected stars for three body fix

(LHA 134*)
Kochab Hc 40* 25' Az 021*
Regulus Hc 55* 59' Az 147*
Aldebaran Hc 29* 32' Az 266*

(LHA 133*)
Kochab Hc 40* 09' Az 021*
Regulus Hc 55* 34' Az 145*
Aldebaran Hc 30* 16' Az 265*

See pic 96 for Pub 249 (42*N)
