The front side of a completed LEO form is shown in Figure 2. All data are 

 entered on the form in the boxes identified by the numbers above them. Each 

 box holds a single number. In cases where there may be more boxes than needed 

 for a given entry, data should be right- justified, i.e., the numbers should 

 fill the rightmost boxes (e.g., entries in Fig. 2 for "breaker height" and 

 "wave angle at breaker").

Figure 2. Typical completed LEO form. 



a. Station Identification (Blocks 1 to 5). Each LEO' site is assigned a 

 five-digit station identification number by CERC. The first two digits indi- 

 cate the geographical location of the site, the latter three digits are unique 

 to each LEO site. 



b. Date and Time of Observation (Blocks 6 to 11 and 12 to 15) . The last 

 two digits of the year and the numerical order of month and day are entered 

 into the appropriate boxes. The time of the observation is by the 24-hour 

 system.
