Very bright red light Hovering in the south horizon.glow very bright red then dim out and random secondary flashes of red

walking in the house when i noticed a very bright red light  Hovering approximately 20-30 degrees in the south horizon seemed to be pretty far away  The light would glow very bright red then dim out and random secondary flashes of red (almost make out a craft but it was very dark outside) it appears to move slightly east(still in southern sky) the altitude of craft never changed observed for an hour watching the craft glow and flash not a strobe effect I was outside 20 minutes prior to event and object was not in sky
