This is a rare craft, and not enough data has been accumulated to give its general configuration.
Report 1
BELL SHAPED UFO WITH STATIONARY YELLOW LIGHT, AND FADING IN AND OUT, RED BRIGHT LIGHT.
I was on the motorway heading towards Plimmerton coming from Pukerua Bay when I saw a Bell Shaped Object in the Sky.
It had a Constant Yellow bright light on it, and also had a bright red light which was fading in and out very slowly… The light could have been rotating like a Light House… I’m not too sure if it was because I was driving …… I’ve seen a plane’s lights before and this didn’t look anything like a plane’s lights And I know it wasn’t a satellite because I’ve seen one of them crash before… I was coming back from delivering some pizzas in Pukerua bay. It was not very far away from the motorway. It was sitting stationary in the sky.
Report 2
Fifteen objects in changing formations seen south-southwest of Nowra. All heading south at first, range from 5 km going away to 15-20 km, then turning and hovering and performing “ballet-like” maneuvers. Total observed time around 30 minutes from 11 pm to 11.30.
Objects seen through binoculars were “bell-shaped with steady light on top and fluctuating colored lights around the bottom rim. All seemed to be translucent“.
