Location: standing in street, border of san marcos and escondido, observed "star" in sw direction. it stayed stationary, same location, as i watched it for 15 minutes. i then got a friend to look at it, and she observed for about 3 minutes, and then it took off in sw direction until out of sight. we observed it with binoculars and it had pulsating colors. streaks/flashes of lights on its surface. as though, you were watching lightning in the sky, but it was "lightning" on the surface of the cone shape "star" looking ufo. colors: red, yellow, green, white,and very brilliant (not dull), lights. it would show a flash of color (light up, like lightning) and when the color wasn't flashing, the ufo looked white, and shiney, like a star. i would have thought that maybe it was a star, except for the flashing, random lights... i knew stars don't flash brilliant reds, greens, etc. and when it took off,( after my friend watched it for 3 minutes), that confirmed it was not a star.
