red light over Tijuana Mexico viewed from Spring Valley

It was early dusk halloween when my daughter (4.5 years old) at the time noticed a bright red light cruising in a westerly fashion in the southern sky.  She had called me downstairs to witness this bright orange to reddish light.  I noticed that it was high in the sky and appeared to me to be moving slowly.  It was very peculiar to say the least.  It was so strange that even my wife who was upstairs getting my son ready for trick or treating that night came out to witness it as it sped up and moved in a straight line pattern but in an vacillating fashion.  I was surprised to see other planes move normally against the same  panoramic view of sky. Which gave me a convincing feeling upon comparison that it was not a normal flying craft.  It was hard to tell how high it was but it was certainly much higher than the airliner traffic whooshing faster than the object appeared to be moving.  Erratically this red light started to vacillate to white and then red and the end made a very steep upward climb out of our sight.
