Bright star like object moved from W to E @ a slow pace, for approx. 15 min. w/ fading brightness in & out.Was @ Frio River, night was clear and warm, stars were bright. It caught my eye first because I thought it was a falling star. I pointed the object out to my friend, he too, saw it. This object was far away in distance, higher than a plane would fly, but just as bright as a star is, only this would fade in & out slowly, you would see ifthen it would dissappear for a minute, it was moving from W to E @ a very slow &steady pace. It lasted for about 15 minutes before the shining object just dissappeared into the night sky. I really believe I witnessed something, my thoughts, it's definately special.
