Silver Y Moth.
At least I think it is it doesn't look like the similar Ni to my eye.
In years gone by before I was blipping I had been known to shout of Clickychick saying words to the effect of "bring your camera your blip is on the doorstep". That time it was a Cockchaffer" on another a hot air balloon very low over the house.
Today she returned the favour, on first stepping outside she was calling me to come and blip this moth. Being a flier by day and night it posed nicely for long enough. Found throughout the UK it is classed as an immigrant as the early stages can not survive the winter.
