three star formation as big as formation at an airshow

three stars in a symetrical triangle started to move slowly from north to south as in the same trajectory as my earlier sighting of bright three pointed star. isighted thie earlier one with my brother and the latter one with my girlfriend and they both were definitely affected by what we saw on both occasions. the three star formation was like three separate parts but moved in unison as one at the same rate and did not appear to disrupt the original pattern. they moved very slowly, i am loathe to say this but like a destroyer in star wars the movie!?! anyway during both these sightings different people were with me and saw the same thing as i and with the same amount of excitement as myself. it is also interesting to note that when i went to get somebody else to witness the events that as soon as i got somebodys attention( the first time via phone to my colleague and the second to my ex wife and kids the objects faded in a matter of seconds.)
We suspect the witness may have observed the three satellites often seen to orbit in formation, which are thought to be part of the U. S. Navy "NOSS" satellite system.  PD
