The domed saucer had lights around the dome, and hovered close to the ground-with a loud humming noise.

I had just gotten home,(way back in the country).  It was about twilight. 
It appeared out  of no where. It was a few feet away from me.  It was a disk, saucer shape with the dome having lights lit up and encircling the dome part.  There was a loud humming sound. 
I was so shocked that I went into the house.  When I came back out to look, the saucer was still hovering above the ground-only a few feet above the ground. 
About that time my Mom came around the bend and the lights from the car seemed to make it take off. It was gone in a split second. 
My Mom & I stayed up til about 3am looking for the craft to return. The next morning we checked the ground and all around, hoping to find any evidence.  We found none.
Witness implies that the date of the sighting is approximate.  PD
