High altitude, three craft formation travelling southeasterly above San Jose, CA, August 21 at 23:15

At 23:15 hours on Aug 21, an amateur astromnomer and I observed three objects traveling at a high altitude and flying in a formation that resembled a right triangle. Apex of triangle was in direction of travel. The objects were on a south easterly trajectory that placed them between the summer triangle and the star Vega when observed from San Jose, CA.  These objects did not change position relative to each other were high enough to appear as satellites.
 The objects were of varying brightness and lost their illumination when they entered the earth's shadow.
 Two emails have been sent to [email protected] of NORAD or space command with no response or acknowledgement.
We suspect that the objects may have been the three satellites that have been reported quite frequently during August 2004, which are thought to be three satellites from the U. S. Navy "NOSS" satellite program.  However, that is only a guess.  PD
