Khara – Rama fight – 28 March 12210 BCE: Part 1

A reader wrote …

“I couldn’t replicate the sky situation during the proposed time of the Khara-Rama fight (28 March 12210 BC) with Stellarium. I didn’t see the eclipse, and some of the planets were below the horizon at the stated time of 4:40 PM.”

I feel delighted when I receive emails likes these. As one reader wrote previously, “This is a book (referring to HR) to be read with pen and paper on the side.”.

To understand something (either Ramayana or Mahabharata) is to read it and start finding problems with it. And to understand a problem is to try solving it, and fail at it.

It is important to realize that reliability/accuracy of astronomy simulations go down as one goes far back in antiquity (and if one goes far in the future). Especially the position of the moon (this is being most difficult to predict) is affected the most (in addition to the fact that ‘Delta T’ correction can add +/-2 days of variation for say ~5000 BCE timeline and even larger variation as one goes back further, in antiquity). The angular separation (between Sun/Moon/Earth’s shadow) estimates are also affected, as one goes far (backward or forward), from the present, with astronomy simulation.

I encourage all to check the positions for the above date, using any astronomy software they have access to.

This is a good Gage R&R study

Per Voyager 4.5 (Carina soft), the positions on 28 March 12210 BCE (at 4:50 PM) at Nashik (one may use Mumbai, Delhi, etc. in their simulation and it should not make significant difference)

All the planets/moon/sun were above horizon at 4:50 PM.

(I have noted down positions of Uranus, Neptune and Pluto, in orders for others to have additional data points to check the reliability/accuracy (and thus variability with respect to Voyager 4.5).

From East to West. (in Right Ascension, Dynamic Epoch)

Uranus – 5 hr 24 min
Saturn – 4 hr 37 min
Neptune – 1 hr 19 min
Mars – 22 hr 4 min
Pluto – 19 hr 55 min
Venus – 18 hr 51 min
Sun – 18 hr 43 min
Moon – 18 hr 39 min
Mercury – 18 hr 24 min
Jupiter – 17 hr 47 min

  2. Hi,
    Following are the RA positions of the planets, sun & moon on 27th & 28th March 12210 BC as shown by Stellarium (version 0.12.4)

    We need to select Custom equation of Delta T. I used,
    ΔT = -20 + 32 * u^2
    where: u = (year-1820)/100
    (http://eclipse.gsfc.nasa.gov/SEhelp/deltatpoly2004.html)

    Also the Stellarium uses astronomical year convention. So any year in BCE will be represented as -ve value and 1 BCE will be year 0, 2 BCE will be yr -1, 500 BCE will be yr -499, 12210 BCE will be yr -12209.

    Nashik, Maharashtra
    27 March 12210 BC 04:15 pm (-12209/03/27)
    lunar month/tithi : Ashaadh Amavasya

    Uranus – 5 h 16 m (58 s)
    Saturn – 5 h 25 m (20 s)
    Neptune – 1 h 11 m (27 s)
    Mars – 22 h 15 m (19 s)
    Pluto – 19 h 38 m (33 s)
    Venus – 18 h 49 m (27 s)
    Sun – 18 h 41 m (49 s)
    Moon – 18 h 34 m (0 s)
    Mercury – 18 h 02 m (37 s)
    Jupiter – 17 h 34 m (15 s)

    28 March 12210 BC 04:15 pm (-12209/03/28)
    lunar month/tithi : Shravan shuddha 1

    Uranus – 5 h 16 m (49 s)
    Saturn – 5 h 25 m (02 s)
    Neptune – 1 h 11 m (27 s)
    Mars – 22 h 17 m (37 s)
    Pluto – 19 h 38 m (40 s)
    Venus – 18 h 54 m (43 s)
    Sun – 18 h 45 m (58 s)
    Moon – 19 h 38 m (10 s)
    Mercury – 18 h 00 m (54 s)
    Jupiter – 17 h 35 m (13 s)

    The software does not display the lunar tithi/month (at least I don’t yet know the configuration to make it display) but you can figure out the tithi of moon (at least on these two days) by just looking at the position of sun & moon.

    On 27th March at 4.40 pm, the RA’s of sun & moon are the same as that of at 4.15pm given above (difference in seconds) but jupiter & mercury are just below the horizon.
    Stellarium is not showing ‘eclipse position’ of sun & moon but they are close enough.

    So Stellarium shows amavasya on 27th March & not on 28th. The sun is approx. 10 days ahead from winter solstice. I’m not sure whether this can be called a solar eclipse or not. But it does show the scenario very close to what Voyager has shown (difference of 1 day & differences in positions of Jupiter & Saturn).
