Recently, Jinan Seven Star Observatory photographed "UFOs" 33 times in 6 days, causing widespread concern and controversy. First, at about 2 a.m. on September 1, a black track rose rapidly and then disappeared in a straight line on the mountain in the distance.

Then around 5 a.m. on September 5, four black ring-shaped objects appeared at the same location, with arc-shaped trajectories, and then disappeared.

Finally at 8 pm on September 6, a linear luminous object slid down in a curve and finally disappeared next to the woods.

Niu Guihua, Vice Chairman of the Shandong Astronomical Society and Secretary-General of the Jinan Astronomical Society, pointed out that until the identity is clarified, these three UFOs can all be identified as UFOs.

However, this statement has been questioned by many experts and astronomy enthusiasts.

Liu Boyang, a Ph.D. in astrophysics, pointed out that UFOs have gone from being a simple concept of UFOs to becoming inextricably linked to occultism, urban legends and even cults, with a strong sense of pseudo-science and anti-science.

The so-called UFOs these past few times, have been preliminarily confirmed by experiments to be the smear of birds, insects or bats captured by a certain surveillance camera that turned on the "temporal noise reduction" (multi-frame superposition) function, and has been recognized by many people in the industry.

However, there are still people (alluding to Niu Guihua) who identify it as a UFO through the media, which is a major misleading to the public.

The result of Liu Boyang’s processing of bird flight photos looks very much like a UFOT AGPH33

Niu Guihua has been kicked out of a well-known domestic astronomy enthusiasts group chat for repeatedly "ignoring" the objective analysis of astronomy enthusiasts.

Niu Guihua expressed regret for this.
