Whenever I travel to Lakeview manor, I always see some strange shimmering light radiating from a light that I assume to be the sun, even if it's nighttime. It usually happens whenever I fast travel, or when I come out of the enchanters tower. I'm on the Xbox so no mods, but I have no idea what it is or what is causing it. Any ideas?

Could be the aurora borealis after image on where the sun or one of the moons crosses the sky.
