Navigation Question

[Cavell]

I'm probably missing something painfully obvious, but I'm having a hard time figuring out where flash traffic's potentially advising me to go in RSRD. The messages all come in with IJN or convoy positions listed in a format like this: "1150N 13152E", and I have no idea how to figure out where that is on the map. Doesn't appear to refer to degrees of latitude and longitude, so I'm at a loss, and would appreciate any help in deciphering it.

Cavell,

The position "1150N 13152E" refers to latitude and longitude.
1150N refers to latitude 11 degrees 50 minutes North and
13152E refers to longitude 131 degrees 52 minutes East.

So looking along the sides of the map to find the corresponding degrees of latitude and longitude. Latitude are horizontal and longitude are vertical lines on the map. Also there are 60 minutes of 1 degree of latitude or longitude.

Hope this helps
