Analysing the Bristol sighting from last month - lens flare or genuine object?

Someone posted a video on TikTok of a sighting over Bristol from August 23rd around 7:15pm. It's since been taken down from the main platforms but I managed to grab a copy. The object appears to be triangular, moving against the wind (you can see clouds drifting the other way), and it's got these distinct pulsing lights along each edge.

I've run it through several analysis tools and the object doesn't match any known aircraft in the Bristol airspace that evening. Some people are saying it's lens flare, but the reflection moves independently of the camera shake and there are multiple distinct points of light that don't behave like typical lens artifacts.

I've attached some screenshots showing the object in different frames. Would appreciate some proper analysis from folks who know their stuff - trying to figure out if this is worth reporting to the Ministry of Defence or if I'm just wasting my time. The person who filmed it says they got a weird feeling while it was overhead, tingling sensation in their arms.

Right, I've looked at your frames and honestly my first thought is a Chinese lantern. They can move in strange ways depending on air currents, and the 'pulsing' effect could be the internal light source being obscured by the paper structure as it tumbles. The fact that it looks triangular is probably just perspective and the way we're viewing it relative to the camera angle. The Bristol airspace is quite busy though, so good idea to check against flight radar data from that evening.

This is interesting. I've been analysing military vessel movements and the pulsing frequency you've captured actually matches patterns recorded at Skinwalker Ranch. That's not a coincidence - there seems to be a global correlation between these sightings and certain electromagnetic frequencies. The 'tingling' the witness felt is classic high-EMF exposure. This could be one of theirs.

How did you confirm the wind direction? Just asking because if you're relying on clouds visible in frame, atmospheric wind patterns can be weird at different altitudes. There could be a strong jet stream pushing the object one way while ground-level winds go another. Not saying it's definitely a lantern, just that the 'against the wind' bit needs more rigorous checking.

The video quality is too compressed to draw any real conclusions. You'd need the original uncompressed footage, metadata from the camera, and ideally corroborating footage from other angles. TikTok compression destroys detail that might help identify whether it's a genuine anomaly or some prosaic explanation. If you can contact the original filmer and get the full-quality file, that would help massively.

MoD won't do anything with this, just so you know. They officially claim they don't track UFOs and all sightings are either misidentifications or weather phenomena. There's a freedom of information request from 2009 that basically confirms they don't investigate anymore. Your best bet is submitting it to MUFON UK or similar organisations that actually care.
