Image collection

Leicester University Archive

An archival collection of c. 1100 images of archaeological and archaeoastronomical interest has been available on-line since 1995.

Basic declination calculator

Version v1.0 (3.6.2013)

This calculator uses the same formulae as “GETDEC”, the program referred to in Astronomy in Prehistoric Britain and Ireland (p. 169) and in various publications by myself and others.

The original program, which will only run under older versions of MS Windows, is accessible on this archival page.



Latitude:

Azimuth:

Altitude:

Notes

Except in discussing putative high-precision lunar phenomena, the apparent declination is sufficient for all archaeoastronomical purposes. While the program quotes results to arc-second precision, a precision of 0.1 degrees (6 arc minutes) is quite sufficient in most contexts.

The program applies a mean refraction correction to the observed altitude and (for geocentric lunar declinations) mean lunar parallax.

See the Astronomy boxes in Astronomy in Prehistoric Britain and Ireland for more information.

Archaeoastronomy

… is the study of beliefs and practices relating to the sky in the past, especially in prehistory, and the uses to which people's know- ledge of the skies was put.
