One of the interesting sights in the night sky are the Naval Ocean Surveillance System (NOSS) satellite formations, each having two or three satellites in close proximity to one another. Normally these satellites are relatively dim to the unaided eye, but on occasion they brighten sufficiently to be easily seen in a dark sky.
Normally, under favourable circumstances, 2nd generation NOSS satellites reach magnitude +5 to +6, observable with 7x50 binoculars. Occasionally, they brighten to magnitude +2 to +4, readily visible to the un-aided eye.
Rarely, they outshine the brightest stars. One observer of such an event commented, "Imagine seeing Venus in formation with itself separated by less than 7 degrees, with Saturn trailing along; that's what the spectacle looked like."
