Celestial visibility is the study of the limits of observability of objects in the sky, with application to deducing the truth about historical events or to the derivation of astronomical information of modern utility. This study is based on what is seen by ordinary humans, either in their everyday lives or at times of historical events. The results of such studies have more relevance to non-scientists than does any other area of astronomy. Celestial visibility is a young discipline in the… Expand

Basic techniques of Computational Astronomy are reviewed and presented as the essential tools for simulation of Lunar phenomena. The importance of accurate determination of Julian Date and the LocalExpand
Toward an atlas of the number of visible stars
Abstract Modelling techniques for the propagation of light pollution in the atmosphere allow the computation of maps of artificial night sky brightness in any direction of the sky, involving a largeExpand
Lunar Crescent Visibility
Abstract We report the results of five Moonwatches, in which more than 2000 observers throughout North America attempted to sight the thin lunar crescent. For each Moonwatch we were able to determineExpand
An evaluation of astronomical observations in the Irish annals
Abstract The astronomical entries scattered through the Irish annals have been examined in a serious astronomical context by R. R. Newton as part of his research into the accelerations of the earthExpand
The Thousand Star Magnitudes in the Catalogues of Ptolemy, Al Sufi, and Tycho are All Corrected for Atmospheric Extinction
Three pre-telescopic star catalogues contain about a thousand star magnitudes each (with magnitudes 1, 2, 3, 4, 5, and 6), with these reported brightnesses as the original basis for what has becomeExpand
Functional forms for approximating the relative optical air mass
[1] This article constitutes a review and systematic comparison of functional forms for approximating the air mass from the zenith to the horizon. Among them, we find the most meaningful forms inExpand
Naked-eye star visibility and limiting magnitude mapped from DMSP-OLS satellite data
We extend the method introduced by Cinzano et al. to map the artificial sky brightness in large territories from DMSP satellite data, in order to map the naked-eye star visibility and telescopicExpand
A re-evaluation of the eastern and western records of the supernova of 1054
Abstract The Chinese and Japanese records are our primary evidence of the supernova of 1054. But their evidence is not entirely consistent, and recent scholarly discussion of them has not yieldedExpand
Archaeoastronomy: A Sustainable Way to Grasp the Skylore of Past Societies
If astronomy can be understood as the contemplation of the sky for any given purpose, we must realize that possibly all societies throughout time and in all regions have watched the sky. The why,Expand

America's first urban centers may have been located in the Supe Valley, Peru. After investigating the location and the orientation of the main built structures, we show that it is not only theExpand


1. PREFACE Despite recent advances in the use of spacecraft as observatory platforms, much astronomy is still conducted from the surface of the Earth, as the existence of an IAU Commission on SiteExpand
The Visibility of Stars in the Daylight Sky
From the theory of the passage of light through a telescope and into the eye, formulas are derived for the improvement in the visual threshold of a point source, as a star, viewed in a field ofExpand
Lunar occultation visibility
Abstract This paper presents a theoretical and observational study of the visibility of stars during lunar occultations. The theory includes the effects of varying background brightness (fromExpand
Astronomical Refraction–Some History and Theories
Astronomical refraction has had a long and fascinating history. Cleomedes (100 A.D.) and Ptolemy (200 A.D.) were aware of its existence and understood in a qualitative way some of its properties.Expand
The prediction of the magnitude of the faintest star visible through a telescope by a visual observer is a difficult problem in physiology. Many prediction formulas have been advanced over the years,Expand
The Visibility of Stars Without Optical Aid
It is generally stated that the faintest stars readily visible to the unaided eye under ordinary conditions are of the sixth visual magnitude. To judge from the limiting magnitudes of the majority ofExpand
Atmospheric refraction and extinction near the horizon
In the past three centuries much theoretical work has been done on the problem of atmospheric refraction. Around 1850 it could be said that the subject was practically exhausted and that littleExpand

The first visibility of the lunar crescent
Abstract The problem of predicting the moment when, after conjunction, the new crescent will become visible is both astronomical and physical. Although realized already by Ptolemy, the actualExpand
Size, shape, and contrast in detection of targets by daylight vision; frequency of seeing and the quantum theory of cone vision.

Frequency-of-seeing curves have been obtained for targets having various image perimeters at background brightnesses of 2950 and 17.5 foot-lamberts, respectively, indicating that in order to detect the target, at least one of the cones along the boundary must absorb at least 4 quanta. Expand
