(10) Lightning. When lightning is observed at a manual location, the frequency and location is reported. 

When cloud − to − ground lightning is detected by an automated lightning detection system, such as ALDARS: 

[a] Within 5 nautical miles (NM) of the Airport Reference Point (ARP), it will be reported as “TS” in the body of the report with no remark; 

[b] Between 5 and 10 NM of the ARP, it will be reported as “VCTS” in the body of the report with no remark; 

[c] Beyond 10 but less than 30 NM of the ARP, it will be reported in remarks as “DSNT” followed by the direction from the ARP.
