For the sunglint to appear the sea must have been exceptionally calm, due to low wind, plus possibly some oily film on the surface.

North and south of the column, waves blur the Sun's reflection. The column's diameter is just over 40km.

Morning sunglint occurs every day on reflective surfaces, usually water. It is dependent on the relative position of the Sun, reflective surface and the satellite.

When the angle of the Sun is in the perfect position then total reflection occurs.
