  1. Hi
    Thanks for the new version of UrukFSP. It looks like everything is working as it should. The only thing I would like to see is the addition of information about moon obscuration in percentage. Like Xavier M. Jubier has on his site.

    Regards Kamil

  2. Hi
    I just downloaded version 1.4.5_1. I haven’t had time to test all the new features but everything seems to work perfectly.
    Nice work.
    Regards

  3. Visionata in prima lettura la nuova versione 1.4.5_. Al momento non riscontro anomalie.
    Grazie.
    Luigi

  4. Hi
    Version 1.4.5_2, menu PREFERENCES – DE441- Files Path the “Changes” button is blackened.

    Regards

  5. Hi
    Same problem as Kamil with version 1.4.5_2.
    However, when I click on the black button, I can change the directory.
    Regards

    1. Hi
      Of course, even the blackened button is still functional. I always have to re-select the folder with the DE441 files every time I install a new version. Otherwise, from my point of view, everything works as it should.
      Regards

  6. Mayunk Vahia’s follow up article to ,An Examination of ‘Atri’s Eclipse’ as Described
    in the Rig Veda called, ‘Tilak was Right : Aaryan Did Come From Arctic’
    (2024) See Researchgate.net/Publication/385476535.

    It appears that Mayunk Vahia has shot himself in the foot over the previous co-authored
    article with Mitsura Soma on ‘Atri’s Eclipse’.

    In the Tilak article Nov.2024) it shows he is in the Aryan Invasion theory (AIT) camp
    opposing the Out of India Theory (IOT) camp. He claims Indians descended from a particular
    spot or place in the Caucasian Region of Russia and migrated into India later.
    The location he lists is Lake Issyk Kul in East Kyrgyzstan. The article looks like
    it was hastily put up on the website. There are no page numbers even though the Contents
    Page lists the page number for each section. Figures are out of numerical order
    and some parts are repeated in the text.

    In the section on the location of the Rig Veda ,he drops a clanger, bomb shell by
    stating that there is no mention ,whatsoever, of the Sanskrit word ,Mrigashirsha
    (also spelled as Mrgasiras) for the constellation Orion (See Section, Solstice
    Ratio and the Composition of Rig Veda) ANYWHERE in the Rig Veda. I checked this out
    from another Indian author, from the OIT camp, Shrikant Talageri (see https://
    Talageri.blogspot.com for Dec 2017 article) and it’s true.

    For the Atri ‘eclipse’ paper it is stated that the authors had two constraints
    to search for the ‘eclipse’, 1) Sun three days before Autumnal Equinox and
    2) Sun in Orion at vernal Equinox.

    The last constraint is now clearly voided. It gets worse. To have one of the
    two possible ‘eclipse’ dates ,3811BC shadow path go over Lake Issyk, Vahia
    recalculated its path again (assumed so here).That is shown on Figure 3 in
    his Tilak article but labelled as Vahia and Soma 2023. When you zoom in on
    the delta t value it shows 43,000 seconds as opposed to 130,000 seconds
    in the Atri article (Vahia & Soma,2023,407,Section 4).This is impossible
    for such an early date year as 3811BC (although it could be a mistype ).

    That’s not all, remember they used genetics to claim a location near the
    Caspian Sea. It now appears that the genetics map for that is one of
    many possibilities that they cherrypicked or zoomed in on (see figure 14 and
    paragraph directly underneath it).

    This now means they have no specific location for either 3811BC or 4020BC
    and the only constraint left for searching for an eclipse is the one
    where the Sun is three days before autumnal equinox. However, that mention of
    equinox either vernal or autumnal, is demolished by author Shrikant Talageri.
    See his article on December 2017 on his blogspot.

    In fact, Talageri demolishes any astronomical dating or references for
    the Rig Veda. he states ” No where in the Rig Veda is there any mention
    of equinoxes of any stars of constellations and finding a date to
    ‘match’ Atri’s ‘eclipse’ he states as an impossibility as there are
    no specific details in the hymn verses to do this. There is no mention
    of Orion (spelt in his article as Mrgasiras) anywhere in the Rig Veda.

    He blames early researchers such as Tilak and Witzel etc. for adding
    confusion to the Rig Veda chronology (readers should read sections 2 and
    3 of his long article) In section 3 he lays out the internal relative
    and absolute chronology of the Rig Veda from all the 10 books or 1028 hymns
    and the Atri ‘eclipse mention is in book 5 which he has dated to between
    2200BC down to 1400BC. This he says is based on linguistics, archaeology and
    textual analyses and is irrefutable being based on logic and common sense.
    it does look like researchers trying to date this Atri reference to any
    eclipse are going around in circles and Vahia & Soma’s attempt is just
    one in a number of attempts over the last 20 years which runs into
    dozens of attempts !!

    Hi Paul,
    I’m starting to read the paper you mentioned, “Tilak was Right : Aaryan Did Come From Arctic”. I agree with you, zooming the image showing the path a 43000 DeltaT value appears, absolutely unacceptable. Using the DE441 model, in order to have a comparable path we actually need a DeltaT equal to 131000 secs. More importantly, not having a specific place to work with is a huge problem….

    P.S. It’s not a typo, it’s a missing complete rotation. 43000 + 86400 gives 129400. But with DeltaT full rotations count 🙂

    1. Tilak was not right.
      Thanks for the update Alberto and I never thought of a full rotation.Others on deltat research
      poo pooed anything more than 86400 delta t seconds but they forgot the Moon moves the fastest so even a day rotation will change its position. The indian ongoing debate on Aryanism
      is quite nasty at times and some authors refuse to engage in it. The stake of Indian pride and
      integrity in scientific research on Rig Veda is at stake. I wish them luck.

    Yep, I’ve noted the “bloody black button” on the DE441 change path window. It’s perfectly functional, but shows no text inside. I’m going to solve it while searching other hidden bugs before emitting a 1.4.5_3 version.

  9. I posted this news in Version 1.4.5 Changelog yesterday, so I’m sorry to repost it, but I’m very anxious to get a response.

    Dear Mr. Alberto Cavalli,
    I am passionate and hobbyist.
    I am currently involved in collecting data on astronomical and astrological phenomena in time and space.
    After downloading the URUK FSP v 1.4.5_2 program, I found the following components that aroused my great interest:
    ToolKit 3: Solstices and Equinoxes
    ToolKit 4: Moon Passages to True Nodes
    *Toolkit 6: Standstills
    Toolkit 7: Moon Phases
    Toolkit 8: Moon Perigee and Apogee
    Toolkit 11: Duration of CIV. – NAUT. – ASTR. Dawn (no field to enter the year)
    *Toolkit 17: Moon – Planets Conjunctions/ Occultations

    I would like to review and analyze these data for all the fundamental objects in the Solar System (Sun, Mercury, Venus, Earth, Moon, Mars, Jupiter, Saturn, Uranus, Neptune Pluto) over a period of 30,000 years (JPL DE441).
    Therefore, I would like to turn to you with a question/request/suggestion/
    begging if you could consider, in the next update of the URUK FSP program, adding to the ToolKits section the ability to generate calculations for selected time intervals, such as for example 100 years (2001-2100, 2101-2200, 2201-2300, etc.). Currently, it is possible to generate calculations only for a selected year. In addition, I noticed that in the tools
    Toolkit 7: Moon Phases, Toolkit 8: Moon Perigee and Apogee,
    Toolkit 11: Duration of CIV. – NAUT. – ASTR. Dawn, the date field is missing.
    Due to the fact that the interest in the URK FSP program and the data contained in it is very high, I am sure that adding the option to generate calculations for selected time intervals will effectively increase the attractiveness of the program, enabling faster analysis of so much data in such a wide range of time. If this is not possible or for some reason you do not want to do so, can you at least consider adding the ability to download the generated calculations as a single file (for example, a pdf file) to all Toolkits. Not all ToolKits have this option. Please reply and I would like to send you a warm thank you for your work on the URUK FSP program.
    Yours sincerely,
    Adrian Hynek

    Hello Mr. Hynek,
    In UrukFSP everything is mainly intended for use in archaeoastronomy, so sometimes annual calculations are available and in other cases calculations over longer periods.
    Basically UrukFSP is not a long-term ephemeris generator, but I do not exclude adding Tools that work in this direction in the future. It’s simply a matter of priorities with respect to the things to add.
    As it is, it seems to me that it is already possible to perform analyses that are not possible with other software, but a significant amount of additions are planned for future versions.

    Best Regards
    AC

    1. Hi
      Really interesting. The duration of a total eclipse for Cairo or Giza is around 1 minute. However, for ΔT ≈ 60150s or more, which is within the tolerance for DE441.

      Regards
