Abstract

The analysis of light pollution trends on astronomy websites is of significant importance for the future of observatories. At the time of writing, there are 2225 registered amateur and professional astronomy sites worldwide. In this study, temporal trends for the period 2002-2023 for all these astronomy sites were analysed using satellite data. The Mann-Kendall (MK) and Sen's Slope (SS) statistics were calculated to ascertain whether the observed increases or decreases in light pollution were statistically significant. The analysis revealed a significant change in 570 observatories, with 182 demonstrating a reduction in light pollution and 388 exhibiting an increase.

Özet

Astronomi sitelerinde ışık kirliliği trendlerini incelemek amacıyla yapılan çalışmalar, gözlemevlerinin geleceği açısından büyük önem taşımaktadır. Günümüzde dünya genelinde 2225 kayıtlı amatör ve profesyonel astronomi sitesi bulunmaktadır. Bu çalışmada, tüm bu astronomi siteleri için 2002-2023 dönemine ait zamansal trendler, uydu verileri kullanılarak analiz edilmiştir. Mann-Kendall (MK) ve Sen’s Slope (SS) istatistikleri hesaplanarak, ışık kirliliğinde gözlemlenen artış veya azalışların istatistiksel olarak anlamlı olup olmadığı değerlendirilmiştir. Analiz sonucunda 570 gözlemevinde anlamlı bir değişim tespit edilmiştir; bu gözlemevlerinden 182’sinde ışık kirliliğinde azalma, 388’inde ise artış görülmüştür.
