Solar Eclipses visible from Denmark in the years 1501 - 2600This page describes all total and annular Solar Eclipses visible in Denmark (excl. Greenland and The Faroe Islands) in the years 1501-2600, and all partial eclipses visible 2007-2050. The partial eclipses visible from Denmark:

NotesSourcesThe total and annular eclipses described here were found by manually "scanning" the maps given in the book Canon of Solar Eclipses -2003 to +2526 by Herman Mucke & Jean Meeus (Astronomiches Büro, Vienna, 1983) finding all possible candidates. Using the program OCCULT distributed by IOTA, the final maps were generated. And, of course, the above mentioned NASA Eclipse Home Page by Fred Espenak. The catalog of partial eclipses is prepared, too, on the basis of the Fifty Year Canon of Solar Eclipses: 1986-2035 by Fred Espenak. The two articles from the Danish magazine Verdensrummet (1991 no. 4, p. 12; and 1992 no. 4, p. 14) from Tycho Brahe Planetarium should be mentioned too, especially as an inspiration for this work. The latest Total Solar Eclipse visible from DenmarkAbout the latest Solar Eclipse visible from Denmark, 1851 July 28, see Michael Cramer Andersen: Solformørkelsen 1852 - den seneste totale solformørkelse i Danmark (PDF, 4 MB!)The next Total Solar Eclipse visible from DenmarkThe next Total Solar Eclipse visible from Denmark occurs 2142 May 25. The eclipse is visible in parts of the island Bornholm in the Baltic Sea and perhaps in Gedser -- the southern most part of the island Falster. The first article in Verdensrummet mentioned above, claims that the next Total Solar Eclipse occurs 2426 September 2, but this is not true, as is corrected in the second article.Delta-TThe location of the eclipse path depends (among other things) on the parameter called Delta-T, which is the time between the Dynamical Time (TD) and the Universal Time (UT): Delta-T = TD - UT . TD is a uniform time scale based on atomic clocks, while UT is based on the rotation of Earth which is slowing down. Because this occurs in an unpredictable manner, the value of Delta-T is not well known for the years before the telescopic age (1620) or in the future. This makes the prediction of eclipse tracks uncertain, especially in the extreme past and extreme future (thousands of years). However, models of Delta-T gives approximate values. The values of Delta-T (in seconds for each year between -1500 and +3020) used here (avaiable as DELTAT.DAT, 61 KB) correspond to the models used in Canon of Lunar Eclipses 1500 B.C.-A.D. 3000 by Bao-Lin Liu & Alan D. Fiala (Willmann-Bell, Richmond, VA, 1992). For other values of Delta-T the correction of the eclipse path can be calculated as follows: Shift = 0.00417807 * (Delta-T1 - Delta-T2) , where Delta-T1 is the tabulated value and Delta-T2 is the other value af Delta-T. The shift is measured in degrees and is added to the paths longitudes. The latitude is not affected. MapsEach eclipse is described with two maps (as GIF's, sizes 10-20 KB): An Earth view showing the full area of the eclipse path, and a close-up showing the eclipse path across Denmark and (parts of) surrounding countries (Sweden, Norway, Finland, Germany, etc.). The maps are centered at latitude 58 deg. North and longitude 11,5 deg. East and the width are 35 deg. The maps were processed using the software IrfanView. Partial eclipses and near-missesNot partial eclipses, and no "near-misses" are included (yet). Near-misses means solar eclipses (total/annular) with a central path close to Denmark, e.g. the solar eclipse of 1954 june 30, which was total in the Skagerak. Size of DenmarkThe size of Denmark has varied in the past due to political reasons, but no eclipses has occurred in the affected areas (southern parts of Sweden and northern parts of Germany). DatesDates before the year 1582 are given in the Julian calendar, and dates after in the Gregorian - even though the calendar reform in Denmark first took place in the year 1700. This only afflicts the dates of the eclipses in the seventeenth century. Final commentsThis work presents, to the best of my knowledge, all total and annular eclipses visible from Denmark in the considered period. However, I might have missed some or simply be wrong. If so, please let me know! Further development might include partial eclipses with large magnitudes, near-misses, an extension of the period (most likely), or local circumstances. [Top
