But, if you’re easily scared and think it’s some kind of alien invasion, then you probably need to calm down and talk to someone with a medical qualification, because it’s just a cloud.

The cloud is an altocumulous lenticularis, or a flying saucer cloud.

They are formed when air flows collide with man made objects or mountains and could be seen from Tallaght to Glasnevin earlier today.
