Curiosity took this image of Earth on Jan. 31, 2014, 80 minutes after sunset.

Stellarium has the Earth >15° above the horizon 80 minutes after sunset on that day.

With Stellarium indicating the magnitude of Earth is -1.15, can anything about the brightness (or darkness) of the sky be inferred from this information?

from your profile you are writing a sci fi book yes? From what ive gathered twilight is only a tad brighter than night. – Topcode Mar 31 '20 at 03:22
