At 11:47 pm [tg], a straight light moved from one Altocumulus cloud to another cloud near by, about a 1 mile high or 5 to 6,000 ft at 45 degrees from the horizon as a references point. It was a white and yellow string of solid light, moving in a straight line with impressive speed-not a lighting nor a shoooting star. It was not a shooting star, I have seen many of those, neither was a moondog(nor sundog- it happen at night), nor a halo nor anything analogous to atmospheric phenomena. It looked more like a firework, shooting high in the air, with the exception that I could see the beginning of it, and it was amazing, I was looking of the moon located at the southwest and talking in the phone to my best friend in NV, when I sudendly told him, you won`t believe what just happened here, the phone call ended abruptly w/o neither one of us hanging the phone, he redial me to made sure I was Ok. I described to my friend to the best of my abilities. That thing began swerving [tg] without any light, like a wave of simmering steam emaning from a cloud, it was tranparent and then lit itself with a white and pale yellow light. And it Stretch or extends from a point A to point B, like if someone was drawing it with a crayon made of light a thick line of light. It`s was surreal. It was quite late, so I can say that anyone else in the Houston area saw it too, unless they had happened to be looking of the sky in the precise moment.
