The results of measurements in two series, each series of 4 Runs and about 50 days each Run, are presented. A multi-cathode counter with an iron cathode is used in these measurements. In both series we have observed some excess in count rates in side

The technique is described of the search for dark photons with a multicathode counter. The aim of experiment is to search for diurnal variations of the effect from conversion of dark photons at the surface of the metallic cathode. The results obtaine

The main points of experiment on the search of dark photons using multy-cathode counter are outlined. The evidence base to prove that the observed effect is really from dark photons is formulated. First data on diurnal variations are presented. The p

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 st

We describe the experiment PHELEX (PHoton-ELectron EXperiment) on the search for dark photons of cold dark matter using a technique of multi-cathode counter developed by us for this task. We present the new data, the new upper limit for the constant

In this paper we describe the apparatus used in this experiment and the procedure of data treatment. We give the latest experimental results and discuss the possibility to observe diurnal variations of the count rates due to rotation of the Earth. We

This article describes our approach to quantifying the characteristics of meteors such as temperature, chemical composition, and others. We are using a new approach based on colourimetry. We analyze an image of Leonid meteor-6230 obtained by Mike Han

The possibility to observe the diurnal variations in the count rate of dark photons using the multicathode counters is investigated. We show that placing detectors at three different mines at different latitudes: Pyh\"asalmi in Finland, Baksan at Rus

Here we present measurements of the rates of emission of single electrons from the cathode of a proportional counter filled with a mixture of Ar + CH4 (10%) at 1 bar. We interpret the results as a possible photoelectric effect associated with hidden
