I spotted smoke from a window this evening... not a lot but I kept an eye on it. Checked social media and it has already been mentioned so I didn't call the fire service but I did keep an eye on it. There were 5 little patches smoking and it felt like it would more likely me a controlled burn, though I couldn't see any people through the binoculars. The little fires did go out after a while and I've not seen smoke since.
@overalvandaan That's what I was thinking, but there have been a few moorland fires recently so I thought I'd keep an eye on it in case especially as there was no sign of a person anywhere!
