Artificial light alters natural regimes of night-time sky brightness [PDF]
PMCID: PMC3634108Open access journalArtificial light is globally one of the most widely distributed forms of anthropogenic pollution. However, while both the nature and ecological effects of direct artificial lighting are increasingly well documented ...

Artificial light at night is a top predictor of bird migration stopover density
As billions of nocturnal avian migrants traverse North America, twice a year they must contend with landscape changes driven by natural and anthropogenic forces, including the rapid growth of the artificial glow of the night sky.

Sensitivity of CCD matrices with electronic multiplication
The sensitivity and basic electrical characteristics of the developed direct illumination matrices with charge-coupled devices and electronic multiplication were investigated at room temperatures and low illumination. Photomatrices of 576×288 and 640×512

The red sky enigma over Svalbard in December 2002: a model using polar stratospheric clouds [PDF]
An anomalous red glow due to scattered sunlight was observed at Longyearbyen (78° N, 15° E) on 6 December 2002 from 07:30 UT to 13:30 UT when the solar zenith angle varied between 100.7° and 104°.

Measurements of the Diffuse Ultraviolet Background and the Terrestrial Airglow with the Space Telescope Imaging Spectrograph [PDF]
Far-UV observations in and near the Hubble Deep Fields demonstrate that the Space Telescope Imaging Spectrograph (STIS) can potentially obtain unique and precise measurements of the diffuse far-ultraviolet background.

Tile or Stare? Cadence and Sky Monitoring Observing Strategies that Maximize the Number of Discovered Transients [PDF]
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?

Cloud coverage acts as an amplifier for ecological light pollution in urban ecosystems.
The diurnal cycle of light and dark is one of the strongest environmental factors for life on Earth. Many species in both terrestrial and aquatic ecosystems use the level of ambient light to regulate their metabolism, growth, and behavior.

The Spectrum of the Night Sky Over Kitt Peak: Changes Over Two Decades
New absolute spectrophotometry of the Kitt Peak night sky has been obtained in 2009/10, which we compare to previously published data obtained in 1988 and 1999, allowing us to look for changes over the past two decades.

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 DMSP-OLS satellite measurements of upward artificial light flux and to GTOPO30 digital elevation data in order to predict the brightness ...
