Skylight Events display on the Skylight map as icons. The table below includes a description for each event.
AIS-based vessel behavior events | ||
Standard Rendezvous | Transhipment, bunkering or other rendezvous behavior. Event based on two vessels, both on AIS, within 250 meters of each other for more than 30 minutes. | |
Dark Rendezvous | A single vessel on AIS with behavior indicating a potential rendezvous with another non-AIS transmitting vessel or other irregular movement | |
Fishing | Fishing activity (e.g., trawling, long lining, purse seining, squid jigging). | |
Entry* | User configured entry of a vessel (first AIS signal received) within a single Area of Interest | |
Speed Range* | User configured speed detection by time or distance within a single Area of Interest | |
Vessel Detections Black icons () indicate a detection that is correlated to AIS. | ||
Night Lights | / |
Ability to detect vessels using bright lights. Globally available nightly, but not effective where clouds and moonlight limit visibility. |
Satellite Radar | / |
Vessel detections best suited for vessels constructed of metal. Clouds or other weather does not affect detection ability. |
Radio Frequency | / |
Ability to detect vessels using onboard navigational radar. Not affected by clouds or other weather. |
Optical Imagery | / |
Imagery capable of detecting vessels, including smaller vessels in optimal conditions (clear skies) |
