Measuring Light Pollution with Fisheye Lens Imagery from A Moving Boat, A Proof of Concept [PDF]
, 2017 Near all-sky imaging photometry was performed from a boat on the Gulf of Aqaba to measure the night sky brightness in a coastal environment. The boat was not anchored, and therefore drifted and rocked.

Astronomical random numbers for quantum foundations experiments [PDF]
, 2018 Photons from distant astronomical sources can be used as a classical source of randomness to improve fundamental tests of quantum nonlocality, wave-particle duality, and local realism through Bell's inequality and delayed-choice quantum eraser tests ...

Evaluating the summer night sky brightness at a research field site on Lake Stechlin in northeastern Germany [PDF]
, 2016 We report on luminance measurements of the summer night sky at a field site on a freshwater lake in northeastern Germany (Lake Stechlin) to evaluate the amount of artificial skyglow from nearby and distant towns in the context of a planned study on light

Real-World Urban Light Emission Functions and Quantitative Comparison with Spacecraft Measurements
Remote Sensing, 2023 We provide quantitative results from GIS-based modelling of urban emission functions for a range of representative low- and mid-rise locations, ranging from individual streets to residential communities within cities, as well as entire towns and city ...

Citizen Science Provides Valuable Data for Monitoring Global Night Sky Luminance [PDF]
, 2013 The skyglow produced by artificial lights at night is one of the most dramatic anthropogenic modifications of Earth’s biosphere. The GLOBE at Night citizen science project allows individual observers to quantify skyglow using star maps showing ...

Methods for Assessment and Monitoring of Light Pollution around Ecologically Sensitive Sites
Journal of Imaging, 2019 Since the introduction of electric lighting over a century ago, and particularly in the decades following the Second World War, indications of artificial light on the nighttime Earth as seen from Earth orbit have increased at a rate exceeding that of ...

Night-time monitoring of the aerosol content of the lower atmosphere by differential photometry of the anthropogenic skyglow [PDF]
, 2020 Nighttime monitoring of the aerosol content of the lower atmosphere is a challenging task, because appropriate reference natural light sources are lacking.

Tile or Stare? Cadence and Sky Monitoring Observing Strategies that Maximize the Number of Discovered Transients [PDF]
, 2003 To maximize the number of transients discovered on the sky, should sky-monitoring projects stare at one location or continually jump from location to location, tiling the sky? If tiling is preferred, what cadence maximizes the discovery rate?
