Erratic Light Moves Across Sky and Stops Overhead.I saw a tiny white dot come across the sky from low on the horizon as it were a plane or a star. It was silent and slowed to a stop a few degrees southeast of the field I was in and appeared to drift rapidly from side to side, speed up, and slow down moving rapidly in different directions at a very high altitude. It continued moving from east to west in an erratic manner far above the clouds with no jet trails or sound. The object would appear to stop and then dart rapidly as it were moving very fast but over a very small arc less than a tenth of a degree. It gradually seemed to drift south of me from east to west but approached the area I was in more rapidly slowing almost to a stop. It was partly cloudy and there were no stars in the sky. The sun had set half an hour before. It was around 9:45 PM.At one point it was moving so slowly I thought it might be moving in the opposite direction it came but there was definitely a subtle and rapid darting from side to side. I noticed nothing else in the sky that seemed to reflect or emit light at the time. The dot may have had a slightly yellowish tint. What was unusual was that it seemed to approach the field I was in very rapidly as though it were a plane traveling in one direction and once it were about three or four degrees southeast of me it stopped and drifted very slowly darting around erratically but subtly. I got tired of watching it as it moved slowly south and west from me continuing the erratic darting and slowing as it were not moving quickly enough across the sky for me to watch it go to the horizon. I could not identify the object. It could have been a satellite or space station or something not extraterrestrial, but what was unusual was that it had slowed and stopped a few degrees from where I was and darted around.
