Independent Observations of Daytime Unidentified Aerial Phenomena in Ukraine: High-Altitude Luminous Dark Objects and Short-Lived Phantom Detections

To the point

Two meteor stations in Kyiv and Vinarivka recorded daytime sightings of two luminous dark objects at altitudes of about 620 and 1130 km, moving 256 and 78 km/s, with color indices B-V = 1.35 and V-R = 0.23 suggesting sizes over 100 meters, and these observations are presented as facts without interpretation, while additional daytime sky monitoring using consumer cameras in Kyiv (August–September 2018) and Vinarivka (October 2022) found several cases of dark phantom-like ovals 20–100 meters across lasting a fraction of a second and traveling 2–30 km/s, the report emphasizing kinematics and the physics of celestial bodies, spanning 13 pages and 34 figures, categorized under Popular Physics and Instrumentation and Methods for Astrophysics, and submitted on 13 November 2022 with a DOI.

Unidentified aerial phenomena II. Evaluation of UAP properties

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. Two-side monitoring of the daytime sky led to the detection of two luminous objects at an altitude of 620 and 1130 km, moving at a speed of 256 and 78 km/s. Colorimetric analysis showed that the objects are dark: B - V = 1.35, V - R = 0.23. The size of objects is estimated to be more than 100 meters. The detection of these objects is an experimental fact. Estimates of their characteristics follow from observational data. The authors do not interpret these objects. Daytime sky monitoring in Kyiv with multi-color DSLR camera at a rate of 30 frames per second in August and September 2018 and in Vinarivka with a multi-color CMOS camera in October 2022 revealed several cases of dark objects (phantoms). The time of their existence is, as a rule, a fraction of a second. These are oval-shaped objects ranging in size from 20 to 100 meters with speeds from 2 to 30 km/s.
