Pulsing white light seen again

Early this morning I was sitting outside in the backyard watching the stars (as I am so wont to do nowadays) when I noticed, to the North, a pulsing white light moving in an Easterly direction.  It passed behind some trees, stopped, dimmed, then changed direction and began heading south, (right towards me).  I watched it as it slowly drifted over my head.  Every 3 seconds it would glow white-hot, then fade out.  At arms length, it was about the size of a pea.  This isn't the first time I've seen this craft.  It always seems to show up between midnight and 2:30am.
