What is wrong with my computation about sunrise at Sao Paolo at july
18
2003(three)
lat: 24-20 S long: 47 W
Nautical Almanac 2003
20 6.11
24,20 X
30 6.27
------- --------
10* 17 m Dla = 24.20 - 20 = 4* 20'
Table 1 page xxxii
10-4.20-4.30-17-15 --- corr. = 7 m X= 6.11 + 7 =
6h 18m
long: = 47*
47*/15* = (ZD)3 x 15* = 45*
---------
Dlo 2* conv. arc to time page i
2--- 8 m (w=+)
----------------
SUNRISE
6h 26m
(my navigator light 4.1. prog tells me the sunrise = at 6h 50m) ??????
