Abstract:

The pearled solar eclipse of 1912.04.17 occurred 60 hours after the TITANIC disaster had cast its shadow upon this exciting event. The data collected during this most elusive eclipse are compared to those generated by Xavier JUBIER's 5MCSE, the most up-to date ergonomical solar eclipse simulation freeware,which allows the choice of the DeltaT parameter, as well as the exact GPS coordinates of the observation site such as the balloon Globule at 900 meter over Rethondes, see http://xjubier.free.fr/site_pages/solar_eclipses/xSE_GoogleMapFull.php?Ecl=+19120417&Acc=2&Umb=1&Lmt=1&Mag=0&Lat=49.41497&Lng=2.93697&Elv=900.0&LC=1&Zoom=15&DdT=1
This kind of comparison will be extended to dozen of other solar eclipses spread over four millenia. For the last 4'000 years, the Earth's spin slowdown key-parameter Δ T(t) will be assumed to behave as
D T(t) = 30.65 *t² [s], where t is expressed in centuries.
An appropriate ephemeris SI day, as origin of the time axis, appears to be Julian Day 2'398'000.5.
Excellent agreement has been found between our Geo-Chronological Model and the records described in World Annals of all reliable candidates of ancient solar eclipses. Those data are compiled in the Table SAROS, see http://www;archaeometry.org/saros.pdf .
One might speculate if the seconds in excess of this Model compared to actual DeltaT values is the consequence of recent global warming.
