Is there a word for the area of the sky opposite a sunset? [closed]

Looking for a word which refers to the sky directly opposite a sunset. Naïvely assumed it woulf be called nightrise, but that word does not seem to be in use.

Found a word, noctiluca (from nox (“night”) +‎ luceō (“to shine”), which I've been using as a placeholder, but if anyone other than I reads it, they'll miss the point a bit.

This seems to be the anti-twilight point, but if sky is clear and you see the phenomenon of a reddening at that point, you are seeing the antitwilight arch, more poetically referred to as the Belt of Venus.

A derivation from night+shine might be too close to zodiacal light for those familiar with this sort of terminology. That's basically a diffuse band of light across the sky along the ecliptic plane. Embedded at the brightest point of that band is gegenschein which is at the true antisolar point.

But you're looking at the horizon opposite a sunset, which is not the antisolar point after sunset. The glow remaining there is at the antitwilight point.
