Whilst on passage luminescence was observed on 30 March 2001 at about 1700 UTC. Individual brilliantly-flashing spots surrounded the ship, the distance between them being 4-5 m whilst the period between flashes was approximately one second. Unlike the usual luminescence caused by the disturbance of the ship's wake, these lights appeared to be below the surface and extended to a distance of about 50 m from the ship's sides. The position of the phenomenon when first sighted was 10° 02.4' N, 77° 26.5' W, the sea temperature was 28° and the wind was NE'ly, force 3.
