The Observatorio del Roque de los Muchachos (ORM), in the Canary Islands (Spain), was one of the candidates to host the future European Extremely Large Telescope (E-ELT) and is the site of the Gran Telescopio Canarias (GTC), the largest optical infrared facility to date. Sky transparency is a key parameter as it defines the quality of the photometry to be acquired in the astronomical observations. We present a study of the atmosphere extinction at the ORM, carried out after analysis of a… 

Thirty Years of Atmospheric Extinction from Telescopes of the North Atlantic Canary Archipelago

AbstractThis study examines 30 years of atmospheric extinction, τ, obtained from both stellar and solar telescope measurements, at ~2.4 km MSL, from the North Atlantic Canary Archipelago—an island

Atmospheric Extinction Coefficients in the Ic Band for Several Major International Observatories: Results from the BiSON Telescopes, 1984–2016

Over 30 years of solar data have been acquired by the Birmingham Solar Oscillations Network (BiSON), an international network of telescopes used to study oscillations of the Sun. Five of the six

Fraction of clear skies above astronomical sites: a new analysis from the GOES12 satellite

Comparing the number of clear (cloud-free) nights available for astronomical observations is a critical task, which should be based on homogeneous methodologies. Current data are mainly based on

Study of AERONET data of nearby stations in the Canary Islands: application to infer astronomical extinction coefficient at elevated altitudes

In site selection processes, one key parameter is the extinction coefficient. This parameter depends on aerosol load, water vapor content and atmospheric gazes. Actually a lot of satellite

The main contribution to the systematic uncertainties of Atmospheric Imaging Cherenkov Telescopes (IACTs) currently stems from the uncertainty in the determination of atmospheric properties for a

High-cadence spectroscopy of M-dwarfs. I. Analysis of systematic effects in HARPS-N line profile measurements on the bright binary GJ 725A+B

Understanding the sources of instrumental systematic noise is a must to improve the design of future spectrographs. In this study, we alternated observations of the well-suited pair of M-stars GJ

Atmospheric monitoring at the site of the Telescopio Nazionale Galileo

For more than 20 years, the atmosphere above the Telescopio Nazionale Galileo and its surroundings at the Roque de Los Muchachos Observatory have been monitored. From the first instruments installed

Next-generation telescopes with curved focal surface for ultralow surface brightness surveys

In spite of major advances in both ground- and space-based instrumentation, the ultralow surface brightness Universe (ULSB) still remains a largely unexplored volume in observational parameter

The Isaac Newton Telescope Monitoring Survey of Local Group Dwarf Galaxies. I. Survey Overview and First Results for Andromeda I

An optical monitoring survey in nearby dwarf galaxies was carried out with the 2.5 m Isaac Newton Telescope. Fifty-five dwarf galaxies and four isolated globular clusters in the Local Group were
