In May 2023, the main beneficiary implemented additional information days on the issue of light pollution. As part of the implementation of the Carpathian Star Way project, it was decided to inform the public about the project, light pollution and its effects on the environment in all districts of the Prešov self-governing region. We took advantage of the Night of Museums and Thanksgiving March activities in the districts: Bardejov, Stará Ľubovňa, Poprad, Kežmarok, Snina. For a total of 154 participants. A brief overview is in the following table and we also attach a photo gallery.

The Hungarian partner of the Carpathian Star Way project, nature conservation company Rónaőrző, organized a seminar entitled “The night sky as part of the natural and cultural heritage of the region” held on – 3 October 2022.
The seminar took place in Repašská Huta near Miskolc, in the Bükk National Park. The afternoon of the first day of the seminar was devoted to a workshop on the measurement and processing of light pollution data, which was led by Prof. Zoltán Kolláth, who works at the Karol Esztreházy Catholic University in Eger and has been involved in the analysis and interpretation of data in the field of light pollution for a long time.
The evening program of the first day was filled with a tour of the observatory belonging to the Bükk National Park, located above the village of Repašská Huta. The modernly furnished observatory is focused on popularization activities and has been visited by more than 40 thousand visitors since its opening in March 2022.
During the second day of the seminar, contributions were made about the current state of implementation of the CSW project, about the intended publication of a lighting manual for municipalities in the Slovak language and about NP Poloniny. It continued with a contribution about the starry sky as part of the cultural heritage, namely mentions of what was happening in the sky in the culture of the shepherds living in the area of the Hortobágy plain. The influence of the night sky on the quality of life of the Bükk region was the last topic of the seminar, which ended with a discussion and lunch.

Continue readingWhat is Light Pollution?
Most of us are familiar with air, water, and land pollution, but did you know that light can also be a pollutant?
The inappropriate or excessive use of artificial light – known as light pollution – can have serious environmental consequences for humans, wildlife, and our climate. Components of light pollution include:
- Glare – excessive brightness that causes visual discomfort
- Skyglow – brightening of the night sky over inhabited areas
- Light trespass – light falling where it is not intended or needed
- Clutter – bright, confusing and excessive groupings of light sources
Light pollution is a side effect of industrial civilization. Its sources include building exterior and interior lighting, advertising, commercial properties, offices, factories, streetlights, and illuminated sporting venues.
The fact is that much outdoor lighting used at night is inefficient, overly bright, poorly targeted, improperly shielded, and, in many cases, completely unnecessary. This light, and the electricity used to create it, is being wasted by spilling it into the sky, rather than focusing it on to the actual objects and areas that people want illuminated.
Information pavilions

There will be two similar information pavillions build as the infrastructural component of the project. They will be constructed with the same technical concept. The only difference is the diameter of the main dome. In Slovakia it will be 12 m, in Ukraine 9m. The bearing structure of the building is designed as a hemisphere with a circle ground plan. It is made of pine glued wood. In the interior of the dome will be installed furniture (12 tables, 50 chairs, 2 bookcase), presentation and information technology (computer, data projector, audio system, projective screen). In addition to dome, the second part of the pavilion will be the infrastructure: Sanitary facility, water distribution, well, cesspool, sewerage, paved areas and fencing, terrace. Previously planned third pavilion was replaced by major maintenance in the existing building of Uzhhorod National University. Beneficiary 1 will construct its information centre this way – more suitable for the centre of the city. At the Hungarian site no infrastructural component is needed. The House of Nature already serve there as an information centre.
1th project meeting
The first working meeting of the project took place at the initiative of the lead beneficiary in the facility of the Vihorlat Observatory on Kolonické sedlo. It was attended by representatives of three beneficiaries: the Vihorlat Observatory, the Institute of Development of the Carpathian Region and Uzhhorod National University. Representatives of the remaining two recipients were present online on the zoom platform.
Main topics of the meeting:
- Physical handover of the signed project contract and partnership contracts to the Ukrainian beneficiaries.
- Plan of project activities for the next 3 months. The main activity will be the introductory conference of the project. The place of the proceedings was preliminarily determined. Javornik resort in Uzhansky National Park. Date: end of September 2021.
- The funding system at Uzhhorod University was identified as a growing problem. According to the applicable legislation on the part of the Ukrainian beneficiary, the public procurement process can start only after the transfer of the corresponding amount of funds to the account of the organization. On the other hand, according to the rules of the program, the second transfer of funds to the beneficiaries’ account is conditional on the termination of the public procurement of the main infrastructure works. It was agreed that a solution would be sought in consultation with the Economics Department of Uzhhorod University. Deadline 14.7.2021.
- At the beneficiary no. 4 (Uzhansky National Nature Park) there may be changes in the project team related to changes in labor relations in the organization.
