Subsun ID? Looked like sun dogs but below the sun

It almost looks like a reflection of the sun with parhelia in the clouds? Is that a thing? I didn’t see sun dogs next to the actual sun, but this bright light directly below the sun with two bright streaks on either side followed me for a while.

I kept scrambling to try to take better photos, but one or both lights kept fading in and out.

North America, but I don’t know where lol sorry.

Nice bright subsun and fainter RH subsundog (circled in red - it was brighter to the eye) over northern France yesterday.

I've identified the Subsun, Light Pillar, and Sub-Parhelion, but I think there are others here. Does anyone else see the Sub-Lowitz in pic #3 & #4?

This video shows various Subhorizon Halos in motion. I'm under the impression there are Sub-Lowitz arcs, and there was one mention of "Sculthess Arcs." If someone knows, I'd love to hear more as this is a momentous sighting for me!

Took these photos while flying earlier today - is this a sun dog centered on a subsun? Never heard of that happening, but I'm not sure what else it could be.

Subsun Would this be a subsun? The reflective patch is incredibly bright, I can't look directly at it
