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 installed
in Kyiv and in the Vinarivka village in the south of the Kyiv region.
Observations were performed with colour 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. We call these ships
names of birds (swift, falcon, eagle). Phantoms are dark objects, with contrast
from several to about 50 per cent. We present a broad range of UAPs. We see them
everywhere. We observe a significant number of objects whose nature is not clear.
Flights of a 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. Two-site observations of UAPs
at a base of 120 km with two synchronised cameras allowed the detection of a
variable object, at an altitude of 1170 km. It flashes for one hundredth of a
second at an average of 20 Hz. We use colourimetry 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 colur 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.
