2nd CREDO Visegrad Workshop 2024

The Cosmic Ray Extremely Distributed Observatory (CREDO) is an international scientific programme dedicated to global studies of yet not observed extremely extended cosmic-ray phenomena, the cosmic-ray ensembles (CRE), possibly beyond the reach of existing detectors and observatories. Up to date cosmic-ray research has been focused on detecting single air showers, while the search for...

A presentation often given in schools will be presented. It will be at the popular science level. The conference participants' task will be to provide comments - tips for possible modification of the presentation.

A short invitation to cooperation in a project which will include distribution of small detector arrays to collect data for CREDO. Each array, consisting of several small scintillator detectors in a coincidence circuit, will be able to register Extensive Air Showers and measure secondary cosmic ray flux. They will send data directly to the CREDO database creating network of devices different...

I'll report on the progress with understanding the physics of the cosmo-seismic correlations. The main observations associated with the effect point to the role of both solar magnetism and lunar gravitational forces, although the latter does not appear to have a tidal character. In addition we observe a clear appearance of the sidereal day periodicity in both cosmic ray and earthquake data....

Discussion about the CREDO Master Class Contribution to the Czech Particle Physics Project: https://cppp.web.cern.ch/

In our contribution we will explore the achievements of our extensive research using the neutron monitor at the Lomnicky Stit Observatory in Slovakia. We'll delve into the principles of neutron monitors, which detect secondary cosmic rays produced by interactions between high-energy particles from space and Earth's atmosphere.
By continuously monitoring these secondary neutrons, we gain...

Astrophotography has become quite popular and widespread in recent years by making use of a diverse range of detectors and optics. More and more amateurs or professionals in the field of astrophotography are capturing well-known or less-known objects of the universe and trying to push the limits in the capabilities of their instruments. Astrophotographers' detectors can capture a variety of...

The paper summarizes the scientific and professional research carried out at the Vihorlatská hvezdárna in Humenno during the entire period of its existence. For a long time, expert astronomical observations were mainly focused on variable stars, the solar photosphere and meteor showers. Initially, visual observations were made. In all three areas, they are carried out to this day, which is...

The paper presents the history of observations of variable stars at the Astronomical Observatory on Kolonicky Sedlo. The observational program focused on the research of variable stars is constantly under development. We started with the visual observation of eclipsing binaries. Physical variables were added later. Observations were usually made only during expeditions and astropractices. CCD...
