The object was spotted after a resident was woken by a 'bright white light'.
The resident reported the sighting to police after filming video footage of the 'craft' "turning to her as she looked at it".
Weather conditions at the time were fine and it was not raining, the log states.
The resident told police the UFO - which was spotted in Bradford in April 2018 - 'sounded like a helicopter'.
A police officer was not dispatched to the incident, the log confirmed.
Another caller in Bradford reported a 'triangle shaped red and blue' craft moving in the skies in August 2017.
The log states: "His friend stated it may have been a satellite but he does not think it is."
In August 2015, a Bradford resident also spotted an 'oblong shape with three flashing blue lights' moving exceptionally fast, according to the call log released by police.
