As I was walking across my yard,I heard a deep low humming sound which prompted me to scan the ground around the yard,I saw nothing,until I decided to gaze upward.

As I looked up,I saw a metallic disc shaped craft,hovering roughly 90ft.up.The craft had 2 windows & a oval shaped structure on the bottom which had an array of light which appeared to be rotating.Almost Immediately as I looked up at It,I saw two humanoid like beings staring downward at me.The beings had larger heads than humans,they wore robed clothing,and were about five to six tall. 
The background or interior of the craft was Illuminated In a bright yellowish light.I'd estimate the craft was about 35 to 40 ft.in length & 15 to 20 ft.wide.The object just hovered emitting a deep hum-like sound.The exterior of the craft was metallic In nature having a dull luster,somewhat shiny though. 
About 30 to 45 seconds Into the sighting a third being appeared in front of the ships"window,now there were three beings glaring downward at me.Then about ten seconds later one being,with it's hand gave something small to the other one.As I watched,all three aliens were staring downward at me,which caused some concern,I was thinking something bad was going to happen.My next move was to quickly run into my house & I told my mother about the sighting,which to no avail she didn't believe me.
Witness indicates that the date of the incident is approximate.  PD
