An extremely large and bright, burning light hovering slowly in the sky that was gone shortly after.

I went out into the backyard to let the dogs out, and noticed an extremely bright light in the sky. I stared at it for a moment and it did not appear to be moving, and then I realized it was hovering very slowly in an inconsistent pattern (as opposed to drifting or flying upward on a path). The light was so bright and large that it almost appeared burning, as if it were a large meteor, but the movement of the light made it impossible to be a meteor, because it was not falling down towards the Earth. Another result of the size and pure brightness of the light is that it was very disorienting as far as depth perception; it was very hard to tell how far away it was because of the bright, burning nature of the light. When I say "burning", I mean similar to a pulsating light, but closer to the way light appears to move through a fire. I watched it move for no more than two minutes, then went inside to grab my phone and came back outside (no more than 30 seconds later), and it was gone, which is very strange considering how slowly it was moving.
