Fifth sighting in a week. Obj. was joined suddenly by two identical craft. Disappears from sight. Unknown Field and woods light up by a red light that has no source. Light seems to scan area for about a minute.
Object turns lights on and lands without making a sound.
Country setting in northern Wisconsin with no other houses around. A heavy thunderstorm left the area to the east within the past few minutes. The sky is cloudy with light mist and high dewpoint. Ground area lit up the red light about 100 feet in diameter. Light moves around back and forth and it takes about a minute to cover about 20 acers of woods.
