no sound, very close, translucent metal with shapless orange glow in center of craft.

I was standing on my street corner, around 8pm waiting for some friends, it was dark out and somewhat cold, I just happen to look up and from behind some evergreen trees only about 60 feet or so hi  this disc came out, it was a dull metalic colour, moving very slowly, made no sound, spinning slowly, rocking back and fourth like a boat on water, I could see thru the center of the craft what appeared to be a shapeless florecent glow thru the metal of the craft, it also appeared to have grooves in the craft, I couldnt speak run point, I was totaly frozen, I then ran away and it was gone when I returned with friends,
