| Name | Rebecca S |
| Experience Level | 2/5 |
| Remarks | I was out watering my lawn around 12:30am when I noticed this big bright white ball thing skimming across the sky leaving a bright smoky color trail. I was facing North, it was traveling East. It was traveling very low like it was going down. It travelled in a straight line. All I know is that this thing was huge, bright and going fast. |
