Kyiv has excessive amount of UFOs in the sky, astronomers claim

“We see them everywhere,” the research said. “We observe a significant number of objects whose nature is not clear.”

As a result of the observations made in the village of Vinarivka, located in the south of Kyiv, the researchers explained these celestial objects as “phantoms that are an object is a completely black body that does not emit and absorbs all the radiation falling on it.”

They also stated that UFOs are very fast, and it is very difficult to take pictures.

“We have developed a special observation technique, taking into account the high speeds of the observed objects,” the researchers said.

“The exposure time was chosen so that the image of the object did not shift significantly during exposure. The frame rate was chosen to take into account the speed of the object and the field of view of the camera. In practice, the exposure time was less than 1 ms, and the frame rate was no less than 50 Hz.”

The obvious explanation is that these are missiles, rockets, or other war-related items. However, scientists maintain that their nature "is not clear."

Abstract:

NASA commissioned a research team to study Unidentified Aerial Phenomena (UAP), observations of events that cannot scientifically be identified as known natural phenomena. The Main Astronomical Observatory of NAS of Ukraine conducts an independent study of UAP also. For UAP observations, we used two meteor stations. Observations were performed with color video cameras in the daytime sky. We have developed a special observation technique, for detecting and evaluating UAP characteristics. According to our data, there are two types of UAP, which we conventionally call: (1) Cosmics, and (2) Phantoms. We note that Cosmics are luminous objects, brighter than the background of the sky. Phantoms are dark objects, with contrast from several to about 50 percent. We observe a significant number of objects whose nature is not clear. Flights of single, group, and squadrons of the ships were detected, moving at speeds from 3 to 15 degrees per second. Some bright objects exhibit regular brightness variability in the range of 10 - 20 Hz. We use colorimetry methods to determine of distance to objects and evaluate their color characteristics. Objects RGB colors of the Adobe color system had converted to the Johnson BVR astronomical color system using the color corrections. Phantom shows the color characteristics inherent in an object with zero albedos. It is a completely black body that does not emit and absorbs all the radiation falling on it. We see an object because it shields radiation due to Rayleigh scattering. An object contrast makes it possible to estimate the distance using colorimetric methods. Phantoms are observed in the troposphere at distances up to 10 - 12 km. We estimate their size from 3 to 12 meters and speeds up to 15 km/s.
