A cloud that resembles a UFO has been spotted in the same location for more than 100 years. The phenomenon occurs around the Taieri Plain, an area of agricultural land, to the south west of Dunedin, New Zealand. While many may feel creeped out by the unusual appearance, locals have come to affectionately called it the ‘Taieri pet’.

When waves of air pass over a barrier, like a mountain range, water vapour is forced to condense into vertical layers. This is what led to the formation of ASLCs, as per the National Weather Service.
