GLEAM sources ionospheric position shifts
Nearly 200 hours of observing with the Murchison Widefield Array (MWA) radio telescope during the Galactic and Extra-galactic All-sky MWA (GLEAM) survey were used to assemble... -
Catalogue of Lunar Eclipse Crater Timings
The catalogue contains lunar eclipse crater timing observations made during 94 lunar eclipses in the period 1842 and 2011, together with a reduction of each observation. -
1997 reference of diffuse night sky brightness
In the following we present material in tabular and graphical form, with the aim to allow the non-specialist to obtain a realistic estimate of the diffuse night sky brightness... -
Nutation modeling and VLBI observations
Using geodetic and astrometric VLBI acquired between 1984-1994, we have determined coefficients in the nutation series with uncertainties of 10microarcseconds. This level of... -
Precipitable water vapour at Cerro Armazones
We studied the precipitable water vapour (PWV) content near Cerro Armazones and discuss the potential use of our technique of modelling the telluric absorption lines for the... -
Precession-nutation procedures (IAU 2006)
The 2006 IAU General Assembly has adopted the P03 model of Capitaine et al. (2003A&A...412..567C) recommended by the WG on precession and the ecliptic (Hilton et al., 2006,... -
Methods for CIP and CIO localisation
The precession-nutation transformation describes the changing directions on the celestial sphere of the Earth's pole and an adopted origin of right ascension. The coordinate... -
UT1 definitions in IAU 2000
This paper provides expressions to be used to implement the new definition of UT1 corresponding to the IAU 2000 resolutions either in the new (CEO-based) or classical... -
Celestial Intermediate Pole & Ephemeris Origin
Expressions for the position of the Celestial Intermediate Pole (CIP) and the Celestial Ephemeris Origin (CEO) in the Geocentric Celestial Reference System (GCRS) have been... -
The Raman spectrum of the atmosphere at 23km
Ground-based optical astronomical observations supported by or in the vicinity of laser guide-star systems can be contaminated by Raman-scattered laser photons. Anticipating,... -
O_2_ laboratory atmosphere simulation experiments
Previous studies of haze formation in the atmosphere of the early Earth have focused on N_2_/CO_2_/CH_4_ atmospheres. Here, we experimentally investigate the effect of O_2_ on... -
APEX atmospheric profiles
Ground-based telescopes observing at millimeter (mm) and submillimeter (submm) wavelengths have to deal with a line-rich and highly variable atmospheric spectrum, both in space... -
The Earth as a transiting planet
An important goal within the quest for detecting an Earth-like extrasolar planet, will be to identify atmospheric gaseous bio-signatures. Aims. Observations of the light... -

Earth Orbit, Precession and Insolation -20Myr to +10Myr
La93 is a program for computing the precession and obliquity of the Earth for various values of 1) the tidal effect of the Moon (CMAR) 2) the dynamical ellipticity of the Earth... -
X-ray events in Earth's magnetosphere
We found 217 X-ray brightening events in Earth's magnetosphere. These events occur in the high-energy band (0.5-4{AA}) of the Geostationary Operational Environmental Satellite... -
Seeing Tests for NPOI Project
This paper reports astronomical seeing measurements made at four sites in the western United States during 1991-92. This study was conducted as part of the site selection...
