John,

It is rather simple, stick the thumb into the folded fingers to the
first knuckle and hold it at arms length. That will give you a 10 degree
spread. Each knuckle is two degrees. Top of the knuckle to the hollow
between 1 degree, half way up or down is a 1/2 degree. If your sighting
is between I say plus or minus. ( When voyaging, a 1/2 degree will get
you to 30 miles. A minus gets you inside 30, a plus over 30.

To Calib. your fist and arm, stand in the corner of a room and count how
many fist it takes to get 90 degrees. Ten should do it for most people
but it will let you know what your fist represents

Kind of a fun and easy way to check out things that are happening around
you.

So as of tomorrow the Sun will be 23 1/2 degrees below the Equator.
Subtract that from your local GMT Noon reading and you should have your
local Latitude.

Not sure where your located but St John is about 45 degrees (4&1/2
fists) minus
2 fists and 1 & 1/2 knuckles should be the local sighting (2 Fists and 1
knckle)
Give it a try and a laugh at Ole Thom
