** VERSION 0.9.9.473R CHANGELOG **

1) BUG : Jupiter satellites shadows sometimes were not shown at the correct distance. SOLVED.
2) All the definitions “True Equinox of Date” have been changed to “Apparent”
3) Tycho star names appear with a Zoom factor greater than 100, Hipparcos names with a value greater than 50.
4) When switching to different stellar catalogues the update takes place immediately without the need to upload archives.
5) In Terminal T6 now the limits of the totality/annularity path are completely defined. Code is under test.
6) Longitude and Latitude in the Main Window are handled as decimal values.

7) Found a public domain data source to make an offline world map at:

Natural Earth data in GeoJSON
Public Domain Maps
https://github.com/martynafford/natural-earth-geojson

I transformed all this stuff in several files containing arrays of constants compatible with Pascal, and the job is almost done. This representation of the Earth’s continents is linked with the internal archive of locations and will be used for showing totality/annularity paths of the Solar Eclipse managed by Uruk_One. Partial eclipses are ignored at the moment.

8) The default locations file has been heavily reworked, hopefully correcting all the mistakes contained inside.

9) Two new sections added to Preferences Window. The first one contains some flags used by the new EARTH MAP View, the second one allows to load a reduced dataset for the Solar Eclipses and Lunar Eclipses Canons, from 3000 BCE to 3000 CE. In this way one can have a faster navigation through historical and contemporary eclipses.

10) Starting tests on Eclipses Path. Fingers crossed…….

11) All the definitions of Universal Time contained into Uruk_One have been changed from UTC to UT1. UT1 is the successor of the old GMT, and it is more correct in the astronomical sense to indicate UT. UTC is based on the International Atomic Time and is occasionally adjusted to UT1 through the addition of a leap second.

12) When Longitudine or Latitude is manually changed, the current location turns into “Manual Entry” and the Timezone is intentionally set to 0.

13) Left Click + Button Pressed it is no longer used to move the content of a graphical map. Now a map can be scrolled by moving the mouse over the equatorial or horizontal controls and using the mouse wheel. Four movement steps can be set, 15 °, 1 °, 1 ‘, 1 “. Clicking the left mouse button (without holding the button down) will center the map on that point.

I’m going to publish version 0.9.9.473R of Uruk_One. Actually the code written so far in order to show Totality or Annularity Path of Solar Eclipses must be considered as a work in progress phase. A representation of a central total or annular SE (marked as *TOTAL*, ANNULAR or HYBRID) can be obtained on the new EARTH VIEW selecting the event from the Solar Eclipses Canon (Show Menu), any other type of eclipse (partial, NOC T/A) willl be ignored. Eclipses occurring at high values of Latitude (typically with a value of Gamma greater than 0.92) usually don’t give a complete definition of northern or southern limits so I chose to show only the central line in this case. This happens with the algorithms I’m currently using, of course, so I am still verifying that I’m correctly doing all the needed calculations. I’m pretty sure that this part of code still contains some bug inside so my recommendation is to use this data with care.
