| Name | Dana A |
| Experience Level | 1/5 |
| Remarks | It seemed very close, right above the roof of the house, so I thought it was a drone - only, there was no sound. It seemed to disappear right as it left our view. Was a quite remarkable sight and we agreed it was something we'd never seen before. Four adults all saw it. |
