Sky brightened by large orange sphere that looked like the sun shortly after midnight, slowly dimmed and then descended below tree line

I was watching TV when suddenly the room brightened drawing my attention to the window where it was quite bright outside (not quite like daylight, but much brighter than it should have been for around midnight). I could see a single spherical object that was bright like the sun just above and distanced just beyond the tree line behind my house. At first I was sure it was the moon, but there was no detail to it, just a bright, glowing, orange orb. I approached the window and turns out the moon was higher in the sky and further to the left of my window and was a partial moon, appearing white, not like this radiant, orange ball. This was something else. I began taking pictures with my phone, which unfortunately were not very clear with condensation on the window and my lack of experience with the photo options on the phone. It started very, very bright and slowly began to fade in intensity and drop down below the tree line over the course of about 7 minutes. I did not hear any sound coming from it. There is an empty field beyond the treeline behind our house so I can't explain what it was.
