Is the conjoined UFO a flying saucer or a special shape of the Northern Lights?

1984 February 13 at 8: 00 pm, two meteorological observers (one surnamed Zhang and the other surnamed Feng) in Youqi Genhe, Inner Mongolia, were very surprised to find two extremely bright spots connected together over the northern bank of the Milky Way. After a while, two connected luminaries slowly flew towards them. When you fly close, you can see that it is different in size and looks like a gourd. The major diameter is 2m, and the minor diameter is about1.5m.. Connected in the middle, the big one is in front and the small one is in the back, all of which emit milky white light like fluorescent lamps. They fly quietly, don't rotate themselves, and their shapes and sizes haven't changed, just like balloons played by two children. Five minutes later, they flew to the sky in the direction of Curry and flew to Heilongjiang. ...

This gourd-shaped UFO was found several times in the summer of 1984, and some people took pictures. Whether this conjoined UFO is a real flying saucer or a special shape of the Northern Lights is still a mystery.
