It looked like a firework exploding downward across the western sky but I've seen plenty of fireworks and this wasn't one. It was too large/close and slow to have been reentry space debris, and I suspect the same for it to have been a meteor; I've never seen nor heard of a red meteor either. I saw it through our upper window and wasn't fast enough with grabbing a camera or quick enough to see it cross or intersect with the horizon.
