Description

After the intriguing find of the "circle" in the Calvine UFO photography here (https://www.reddit.com/r/UFOs/comments/wquxbi/messing_with_filters_on…), I looked at the FLIR footage, as it appeared to have the same kind of "anomaly", in TV mode (visible light, as Calvine photo) and seemingly in IR (but not in same spot, maybe due to the spectrum range ?).

Maybe this optical artifact is not directly related to the object himself, or maybe it's a collateral effect of this kind of observation.

Hard to say, but I find it interesting.

FLIR footage used for extracted frame, from https://www.navair.navy.mil/foia/documents :

In TV mode, you can see that effect at the bottom left of the object :

In IR mode, you can see the "circle" above the object :

More specifically in IR mode, you can see that it's present at multiple spot here :

In IR mode it's interesting to see that this effect is no more visible when zoom in (maybe barely the bottom side of the circle in the top of the picture), so it could indicate something space related ?
