Moth on the night of the big thaw

With blanket snow across the country, it may well have been the coldest winter for 2o years , but on the first night of the thaw in which temperatures jumped form 0 - to 6 degrees, I spotted this moth which I think is a Mottled Umber flying against the bed-room window. I'm sure it will survive (although judging by its sub due colours its natural life doesn't have far to go), our garden which had 10 cm of snow just two days ago is now clear.
