Abstract : We describe a system for rapidly measuring the brightness of the night sky using a mosaic of CCD images obtained with a low-cost automated system. The portable system produces millions of independent photometric measurements covering the entire sky, enabling the detailed characterization of natural sky conditions and light domes produced by cities. The measurements are calibrated using images of standard stars contained within the raw data, producing results closely tracking the… 
Campaign of sky brightness and extinction measurements using a portable CCD camera
In this paper, we present the results of a 12-yr campaign devoted to monitoring the sky brightness affected by different levels of light pollution. Different sites characterized by different
Measuring Light Pollution with a Calibrated High Dynamic Range All-Sky Image Acquisition System
Combining series of exposures with different exposure times made with a digital SLR camera and a fish-eye lens allow to create highresolution images that contain the full dynamic range of daylight,
Night sky quality monitoring in existing and planned dark sky parks by digital cameras
A crucial part of the qualification of international dark sky places (IDSPs) is the objective measurement of night time sky luminance or radiance. Modern digital cameras provide an alternative way to
Zernike analysis of all-sky night brightness maps.
The Zernike expansions allow us to quantify in a straightforward way the average and zenithal sky brightness and its variation across the FOV, providing a convenient framework to study the time course of these magnitudes.
Measuring night sky brightness: methods and challenges
Limiting magnitudes and night sky brightness at the Langkawi National Observatory based on observations of standard stars
We present the estimation of limiting magnitudes and night sky brightness at the Langkawi National Observatory with observations of selected standard stars. We first derived the transformation
Imaging and mapping the impact of clouds on skyglow with all-sky photometry
The results show the dramatic increase of the reach of skyglow even for moderate cloud coverage at this site, and the powerful and easy-to-use method promises to be widely applicable for studies of ecological light pollution on a global scale also by non-specialists in photometry.


Night sky brightness at sites from DMSP‐OLS satellite measurements
We apply the sky brightness modelling technique introduced and developed by Roy Garstang to high-resolution satellite measurements of upward artificial light flux carried out with the US Air Force
We have produced a data base of V-band and B-band night-sky brightness measurements rather evenly spread out over the course of a whole sunspot cycle from September 1985 to August 1996. Almost all
Sky Brightness at Kitt Peak National Observatory
Results are reported of a program to determine the brightness of the night sky at Kitt Peak during the recent solar minimum. Well-calibratd photometry in B and V suggests that the average brightness
Sky brightness at the ESO La Silla Observatory 1978 to 1988.
We have measured the sky brightness at the European Southern Observatory (ESO), La Silla, during 40 moonless nights in the years 1978 - 1988. Most of the measurements were performed in ve
UBVRI night sky brightness during sunspot maximum at ESO-Paranal
In this paper we present and discuss for the first time a large data set of UBVRI night sky brightness measurements collected at ESO-Paranal from April 2000 to September 2001. A total of about 3900
Model for artificial night-sky illumination
A model has been constructed to allow calculation of the night-sky brightness caused by a city at its center and outside the city, and at arbitrary zenith distances. A circular city of uniform
The effect of solar activity on the V and B band sky brightness
Measurements performed at San Benito Mountain during 1976-87 reveal that the zenith sky brightness in the V and B photometric bands is well correlated with the solar 10.7-cm radio flux, and thus with
Sky glow and outdoor lighting trends since 1976 at the Lowell observatory
Urban sky-glow (light pollution) trends, recorded photoelectrically in intermediate-band b (472 nm) and y (551 nm) filters at the original site of the Lowell Observatory on Mars Hill near downtown
Atmospheric extinction and night-sky brightness at Mauna Kea
We present a summary of atmospheric extinction values obtained at the 4200-m and 2800-m elevations of Mauna Kea over the years 1980 to 1986. The wavelengths of the 17 filters in question range from
A model previously constructed for night-sky brightness calculations has been modified to allow for the curvature of the earth. The model has been applied to calculate the brightness at the following
