Spectroscopic study of the light-polluted night sky in Hong Kong
Chu Wing So, Chun Shing Jason Pun, Shengjie Liu
Spectroscopic study of the night sky has been a common way to assess the impacts of artificial light at night at remote astronomical observatories. However, the spectroscopic prope…
Natural experiments from Earth Hour reveal urban night sky being drastically lit up by few decorative buildings
Chu Wing So, Chun Shing Jason Pun, Shengjie Liu +4
Light pollution, a typically underrecognized environmental issue, has gained attention in recent years. While controlling light pollution requires sustained efforts, Earth Hour off…
Solar image quality assessment: a proof of concept using Variance of Laplacian method and its application to optical atmospheric condition monitoring
Chu Wing So, Edwin Lok Hei Yuen, Edgar Heung Fat Leung +1
Here we present a proof of concept for the application of the Variance of Laplacian (VL) method in quantifying the sharpness of optical solar images. We conducted a comprehensive s…
Contributions of artificial lighting sources on light pollution in Hong Kong measured through a night sky brightness monitoring network
Chun Shing Jason Pun, Chu Wing So, Wai Yan Leung +1
Light pollution is a form of environmental degradation in which excessive artificial outdoor lighting, such as street lamps, neon signs, and illuminated signboards, affects the nat…
Night-sky brightness monitoring in Hong Kong - a city-wide light pollution assessment
Chun Shing Jason Pun, Chu Wing So
Results of the first comprehensive light pollution survey in Hong Kong are presented. The night-sky brightness was measured and monitored around the city using a portable light sen…
