The Ilkley Moor alien is an alien whose photo was taken during the Philip Spencer encounter in the early morning of December 1, 1987 in Ilkley Moor, Yorkshire, England. The alien was determined to be about 4 foot tall, having a blue-green tint to its skin.
Philip Spencer was walking across the Ilkley Moor in the early morning of December 1, 1987, while heading for his father-in-law's house. On the way, he was hoping to get some photographs of the strange light tricks of the moor. To be able to get the images he desired, he was using a high ASA rated film to compensate for the poor light in the area. He was searching for some photo angles when he suddenly caught sight of a strange looking being, in the slopes ahead of him. He aimed and snapped a picture of the creature which seemed to be gesturing for him to stay away.
