Stationary object in the Desert sky accelerates away at incredable speed.

On or about 01-12-95 at 1:00 AM, I was camped out in a place East of Ransberg California, in the Mojave Desest.  I was doing the usual thing before turning in, which was searching the skys for anything unusual. 
There was an object that was brighter than most in the sky, directly above me. The object was stationary and did not change in shape or brightness.  
My scanning of the skys contiued for about 45 minutes when suddenly the brighter object, directly above begain to move and excelerate Westward. 
As it excelerated, the object appeared to asend, as it was moving away.  It took no more that a two seconds to fade out of sight. 
I got the feeling, either I or the area was being observed.
Witness indicates that the date of the incident is approximate.  PD
