REMARKS: Possible oil was observed in satellite imagery. This anomaly is unconfirmed as oil. The anomaly was discovered 5 NM west of US international water boundaries but had the potential to drift into our waters. The anomaly measured 4.68 NM in length and 0.68 NM in width. Winds were 10-15 kts out of the South.

Confidence that the anomaly seen was oil is Medium-High. The anomaly had high contrast with the surrounding area. The anomaly exhibited feathering that corresponded with the wind direction. The anomaly also had several sharp turns and well defined edges.
