Was sitting in my den, i noticed a white light showing through the open curtain, it was moving from the south west to the south in front of my house about 4 ft off the ground. i pulled back the curtain to observe it, it continued for about 10 ft before it stopped as though noticing me for the first time after about 10 seconds it shot straight up out of sight. object seemed to be intelligent or under intelligent control. orbs are nothing new to my home, but this one was different in it's size and luminous output was significant in comparison to other orbs seen by me. the white color was very much like bright moonlight, soft, non-glaring.
