This report provides a brief synopsis of the campaign and its preliminary outcomes. Section 2 describes the measurement locations, the activities of the participants, the instruments used, and the environmental conditions. Section 3 describes a public outreach event held during the campaign. Section 4 provides some preliminary results, outlines the ongoing analyses, and presents research questions for the next campaign to address. Section 5 provides recommendations for the final LoNNe intercomparison campaign in 2016. Section 6 concludes the report.

Beschreibung: The 2016 LoNNe (Loss of the Night Network) intercomparison campaign is the fourth of four campaigns planned during EU COST Action ES1204. The first campaign took place in 2013 in Lastovo, Croatia, the second in Madrid, Spain (Bará et al 2015), the third in Torniella and Florence, Italy (Kyba et al 2015a). The 2016 campaign took place at the Parc Astronòmic Montsec (PAM). The campaign was supported by the European Collective Awareness Platform for Social and Sustainable Innovation (CAPPSI) STARS4ALL, in which the activity is planned to become a continuous light pollution initiative (LPI). The financing of this campaign, which is listed as a milestone in the MoU of the COST Action ES1204, was unexpectedly waived by the EU-COST Office due to administrative complications and re-organization of the grant-periods. The campaign continued the strategy of taking measurements at multiple sites, this year with a main fixed site and then excursions to other sites. The goals of the campaigns included: ● Understanding the difference between extinction measurements made by DSLR photometry and classical astronomical (telescope) photometry, and also understanding the relation between extinction and sky brightness at these two sites. ● Examining the difference in radiance measured with the mosaic technique of the US National Parks Service camera compared to all-sky fisheye imagery ● Examining the relationships between all-sky and zenith radiance reported by different instruments ● Quantifying the sky brightness at the sites, including full zenith spectral radiance at selected locations ● Measuring the systematic uncertainty on handheld SQM observations due to unit-to-unit differences This report provides a brief synopsis of the campaign and its preliminary outcomes. Section 2 describes the measurement locations, the detailed activities of the participants, the instruments used, and the environmental conditions. Section 3 describes a meeting with local authorities that took place during the campaign. Section 4 provides some preliminary results, outlines the ongoing analyses, and presents research questions for the next campaign to address. Section 5 provides recommendations for future intercomparison campaigns. The Municipality of Balaguer coordinated with us regarding the time that architectural lamps were turned off, and the village of Àger allowed us to turn all street lighting off at a time of our choice.

Beschreibung: Das Bürgerwissenschaftsprojekt Nachtlichter ist Teil des Nachtlicht-BüHNE Projekts (2019 – 2022), finanziert von der Helmholtz-Gemeinschaft Deutscher Forschungszentren (HGF). Im Projekt haben wir einen bisher einzigartigen und weiterhin wachsenden Datensatz erstellt. Hierzu entwickelten wir im Rahmen einer fast zweijährigen, transdisziplinären Teamleistung zunächst eine mobile Web Applikation, die Nachtlichter App. Zum Einsatz kam die App vom 31. Aug. bis 14. Nov. 2021. Über zweihundert Mitforschende zählten und dokumentierten fast eine Viertelmillion künstliche Lichtquellen auf öffentlichen Straßen und Plätzen. Nachtlichter-Kampagnen liefen vorwiegend in deutschen Städten. Dieser Projektbericht dokumentiert den bürgerwissenschaftlichen Forschungsprozess basierend auf sozialwissenschaftlichen Datenerhebungsmethoden wie Interviews, teilnehmenden Beobachtungen und einer Nachbefragung der Nachtlichter-Beteiligten, an der 97 Personen freiwillig teilnahmen. Ausgehend von unseren gemeinsamen Erfahrungen, teilen wir mit diesem Bericht unser praktisch erprobtes Verständnis von Bürgerwissenschaft als gemeinsamen Prozess auf Augenhöhe und unsere Begeisterung. Wir schließen mit drei Vorschlägen für nachhaltige partizipative Forschung.
