Sunset at sea is always a reason to go outside. It can be stunning, in many different ways. The colours, the clouds and, sometimes, the best comes in the milliseconds after sunset.
In this case, I was on the top deck and was looking at the beautiful cloud formations and the colours. Reason enough to pick up my camera. And just when I had my camera on my eye, it happened. The sun set and the last light I saw was a brief green flash! I had seen the Green Flash!! Under specific conditions, sometimes the sun is very briefly visible after sunset in green. A rare event, we have seen many more sunsets at sea, and many people were looking for it, but no green flash was seen anymore.
