REMARKS: Possible oil was observed in satellite imagery. This anomaly is unconfirmed as oil. The anomaly was likely linked to the hotline of the third coast Midstream Pipeline spill. The anomaly was of a silvery sheen with modest contrast with its surroundings, likely indicating a very thin thickness. It was 11nm long and about 1.7nm wide at its widest part. The wind at the time as from the S at about 17 knot.

UNCERTAINTIES: The modest contrast of the sheen with its surroundings, as well as the presence of the clouds, made it harder to mark out the exact boundary of the anomaly, especially at its eastern part.
