EAGLE-EYED Gold Coast residents have been urged to keep a watch for UFOs after a pair of significant sightings near Mudgeeraba.

The central Hinterland area has become a hot spot for UFO sightings, with multiple reports of glowing lights.

Sightings were reported in late March and last month, the beginning of the colder months in which fewer close encounters of the first kind usually are reported.

UFO Research Queensland's Sheryl Gottschall said the durations of the encounters were unusually long.

"A mother and daughter reported seeing two bright red lights nearly half the size of the Moon on April 23 that remained stationary above the road for a few minutes before one took off," she said.

"Several other people reportedly stopped to see it as the second light lingered before disappearing seconds later.

"Back in March there was a sighting above bushland between Robina and Mudgeeraba when a man reported seeing eight bright orange lights above his ex-girlfriend's house."

Mrs Gottschall urged people to continue reporting suspected sightings during the colder months. Reports of sightings to UFO Research Queensland skyrocketed since the Sun published a Varsity Lakes woman's close encounter of the first kind late last year.

Seeing an unidentified flying object is known as a close encounter of the first kind.

Physical evidence brings that rating up to the second kind. Actual contact with a UFO is a close encounter of the third kind, made famous by the 1977 Steven Spielberg Hollywood blockbuster of the same name.
