White UFO spotted near the moon on January 2019

On January 2019, a person living in Kifisia, Greece, has spotted an unidentified white object flying near the moon. What is it?

Witness report:

On January 21st, 2019 i took a few photos of the full moon from Athens, Greece. in one of the photos there appears to be a self-luminous object to the left of the moon with evidence of a trail to its right suggesting it is moving away from the moon. its interesting to see that the object disturbs its immediate surroundings as if it emanates energy. this is not a fault of the camera as the object did not appear in the same pixel area before or after this event.
