I watched one dark grey, silent rectangular object move across my field of vision from south to north very fast on 1/8/09 at 18:09.At 6:09 P.M. CST I went out my kitchen door to take the trash out. The door faces east.The moon is just about full this evening. Out of the corner of my eye, I noticed a strange "cloud" to my right. It was strange enough that I turned to look at it.It was moving from the south to the north very fast. It was about 70 degrees off the horizon and dark grey. The shape is what first caught my attention. Imagine an iPhone lying flat but there was a large "dome shape" under it and in the middle of the rectangle. The "dome" seemed to have several lobes on it so it was not perfectly smooth. In fact the whole object was about the size of an iPhone held at arm’s length. There was only one object.It did not make any sound. In fact I would say the silence was "deafening" in the same way it is quiet after a large snowfall.The moon is quite bright tonight and the edges of the object seemed to glow from the moonlight rather than an internal source. The object obstructed the view of stars as it flew by.I walked down the side path to the front of my house to keep the object in view. It continued straight north. The speed and altitude did not alter. I continued to watch it until it disappeared from view.The sky is clear tonight except for a few wispy, white clouds that are shaped more like long pencils. I watched the object fly under the clouds and noted that the object was not only moving in the opposite direction of the clouds, but it was going much faster than the clouds. It moved fast enough that I knew I did not have time to get my camera. Plus the object was dark enough the I was not sure it would photograph.My dog was outside with me and he started barking when the object was in front of me.I watched the object for approximately one minute before I could no longer see it. There were no aircraft nearby at the time.I was home alone. I am a mom and a business owner. Unfortunately, I did not see any of my neighbors outside who I could ask to witness the object.
