Hovering Aircraft Scanning Fields on Pitney LN, Junction City, OR

I was driving home from my barn on Greenhill Rd.  I could see the aircraft and it had a bright yellow light.  As I drove from Vogt to Hwy 36 the light got brighter.  As I turned down Pitney I could see this object hovering in one place.  About 1/3 of the way down Pitney Ln, I stopped.  This thing was definitely hovering and I could see the underside perfectly.  It was in the shape of a triangle and resembled a jet.  On the long sides of the triangle were a row of  repeating order red, green, and white lights.  It was higher than the light and power poles but not quite as high up at a large plane.  It was poring down rain and I could see every detail on the bottom of the aircraft.  There was also had a light on the bottom of the nose scanning the fields to the left of me and behind me (I was headed to my house by Junction City High School.)  I stopped just for a minute trying to figure out what it was.  I’m used to jets flying around us but this was silent, stayed put, and was scanning the fields.  I’ve never seen a jet do that.  I was cold so continued my drive and it was still there when I turned back.  I probably seen it for a total of 5 minutes (from my barn until I turned down High Pass.)
