A bright not moving object with pulsating red light watched for 45min to 1 hour

I was in bed and was restless when I noticed an unusual light in the sky.  I felt compelled enough to get out of bed and go to the window.  I got my eyeglasses and opened the blinds wider.  I’m not sure how long I was looking at it before I decided to go outside.  The stove clock said 3:20am.  The object was not moving, but it had a faint red light like a beacon going around in one direction.  I stared at it for at 30 mins and took pictures and a video of what I was seeing.  It never moved.   I went back in my apartment but it was still there.  I couldn’t go back to bed.  I fell asleep sitting up on the couch looking at it.  The sun was coming up when I woke up and it was gone.  It hasn’t come back yet but now I’m looking every night.
