There are already a few mods that try to do this, but all the ones I could find either had a bunch of issues or straight up didn't work. So I made one myself.

You can find the spell tome in a chest in the Forgotten Vale's Inner Sanctum (see images).

Functionality: How it works is that while the spell is active, the eclipse will show in the sky all day and disappear at night (if it doesn't disappear at night then Skyrim thinks that the sun doesn't set and instead travels backwards until dawn). It reactivates in the morning. The eclipse effect overrides any weather, so during the daytime you'll only ever have eclipse weather (so no rain or anything like that). Nighttime weather still works as usual.

Cast the spell again to end the eclipse.

If you begin the eclipse during the nighttime then the sun explosion will appear in the sky inverse to where the sun would be on the other side of the world (or in technical terms, on the aforementioned backwards path). It doesn't break anything and the sun will rise the next morning as an eclipse.


It's possible that for a small amount of time after dawn or before dusk the sun will be normal. If you want to avoid this I suggest casting the spell as soon after the hour mark as you can (for example 8:01 would be ideal).
Also sometimes after fast travelling, waiting, or just being in certain areas with specific weather will cause the sun to come out for a bit. From my testing this doesn't happen often and it should be re-eclipsed after an hour.
Regardless of how the sun looks while the spell is active vampires won't take sun damage and the regular eclipse events will happen.

Shooting Auriel's Bow with a Bloodcursed Arrow while the spell's eclipse is active won't do anything, and vice versa.

Now enjoy some Black Hole Sun
