Barn Owl around during the day


I am in East Lancashire and a Barn Owl has been around my garden most of the day.  There are a lot of trees behind my house and I have heard an owl many times over the months in the early evening, but this barn owl sat on the fence for a while today and then went to a tree.  It is sat in the same tree right now washing itself. Is it normal for a barn owl to be awake all day?
