Summer 2023 Yorkshire Moors sighting—object vanishes in thermal imaging

I'm posting this on behalf of a friend who's camera-shy but captured something genuinely unusual in June 2023 on the Yorkshire Moors near Goathland (yes, the Harry Potter village). He was doing astrophotography around midnight on a clear night, using a Canon EOS 7D with a thermal imaging overlay app.

For approximately 3-4 seconds, an object appears in the thermal feed moving at roughly 60mph in a straight line, then abruptly vanishes. Here's the peculiar bit: it disappears from thermal imaging but doesn't vanish from the regular visible light recording. In visible light, it's just a blur that could be a drone, bird, or photographic artifact.

The thermal disappearance is the interesting data. If it's a drone, it should remain visible thermally (warm electronics). If it's a bird, same story. If it's something that can modulate thermal signature or become thermally 'invisible', that's more exotic. Could also be some kind of atmospheric phenomenon.

I'll attach both the thermal and visible light clips. Would appreciate some proper analysis rather than speculation. Has anyone seen similar thermal anomalies?

This is interesting. The thermal disappearance while remaining visible in regular light is definitely unusual. Could be a few explanations: (1) thermal imaging app glitch or frame drop, (2) something that reflects visible light but emits no heat, (3) object passing through a thermal 'dead zone' caused by ambient conditions. The Yorkshire Moors would have variable ground temperatures that could create odd thermal artifacts.

I work with thermal imaging for building surveys. Most smartphone thermal apps are actually quite unreliable - they can struggle with fast-moving objects and often have lag or frame skipping. Wouldn't read too much into the 'disappearance'. The visible light clip is more interesting - can you tell anything about the object's flight characteristics?

Goathland is interesting. That area has been flagged in UFO literature for decades. There's a decent report from 1987 of similar moving lights. I'd be curious if your friend has noticed any odd electromagnetic effects - dead mobile spots, compass problems, that sort of thing - in that location.

Really solid documentation. The fact that it was captured simultaneously in two formats is valuable data. Whether it's something extraordinary or something mundane, this is the kind of methodical approach the subject needs more of. Good work.
