Date of Sighting: May 5, 2009 (Object Has Been Appearing Since April 23, 2009)
Time of Sighting: 8:30 PM PDT (Visible For Several Hours After This Time)
Location of Sighting: Cheney, Washington (Eastern Washington About 10 MI SW of Spokane)

Description: For about 2 weeks now we have been seeing strange lights in the sky. The first time was Thursday the 23rd of April 2009. We were smoking a cigarette around 1:00 AM when an object flew in front of the house with red, blue, and white lights flashing around it. This happened again about 2 hours later. Almost every night since we have seen the lights with the object hovering in one spot. At the same time there will be a second one flying towards it with bright flashing lights, then it disappears. Tonight (May 5th, 2009) we saw a object moving towards the hovering one very fast and very low. This one had only one very bright red light. It was really strange. We have never seen anything like this in our lives.

Note: I don't know what the witnesses have been seeing, but the fact that the sightings have been repetitive suggests a conventional explanation.
