Janesville, WI, United States

Witness Matthew Selck observed a single diamond/pyramidal shaped object at 900-1000 ft altitude traveling SW to NE at approximately 30 mph. The object was roughly the size of a UPS truck and had no exterior lights, instead pulsing from within approximately every second, cycling from bright orangish-white (making the object almost translucent) to dull red (like an ember inside a dark crystal). Movement was smooth and linear. The witness believed the craft was observing neighborhood low-altitude fireworks shells being set off for July 4th. A local police officer on the road appeared to also observe the object and followed it when it disappeared into the trees. The witness's wife also saw the object though did not get as good a look. Approximately 15 minutes prior, friends of the witness observed something smaller, brighter, and faster at a much higher altitude, which the witness later speculated may have been related.
