Sb: Is there a database of star names related to Indian culture
Dear Rear Admiral Vasanth,
Thank you so much for the interest you have taken in getting prepared a table of the nakshatras with their Western/technical equivalents and other useful details like mag, dist, RA, Decl etc. Since the (tropical) coordinates depend on the precession of the equinoxes, it is better to specify the reference year (like 2000 CE, 2011 CE). For example, in my book "Indian Astronomy - An Introduction" I have provided a similar table (pages 3a 5-37).
That table (Table 4.3) includes "Nirayana" (Sidereal) longitude and cel latitude ("shara" or "vikshepa" in Sanskrit. The interesting thing is while the tropical ("Saayana") coords go on changing due to precession of equinoxes ("Ayanaamsha"), the sidereal coords remain constant (of course ignoring the negligible proper motion of stars!).
In your yet to be completed table, you may please include the following special stars (not among 27 stars) which are supposedly visible to the naked eye:
Reference date: 1995.0 = 1995, Jan. 0.822 UT

A comment on the "sidereal ("nirayana") longitudes used in Indian classical astronomy: While the rate of precession of the equinoxes (or the solstices) is precisely known scientifically, the year and date when the "zero" point (“Mshaadi”) of our Indian fixed zodiac coincided with the first point of Aries ("zero" point of the moving zodiac) is an unsolved problem ! The problem being "domestic" (peculiar to Indians!), modern astronomy cannot solve it!
While Govt of India, in its publication of the "Rashtriya Panchanga" (in 13 languages), has adopted March 22,285 CE as the "zero ayanaamsha" date, other learned scholars do not accept this date! They suggest a year around 522 CE (Aryabhata's time) as the "zero year". Therefore, when you mention your and your wife's nakshatras to the priest, actually those may not be your birth-nakshatras at all. In other words, while the priest pockets your 'dakshina" the fruit ("punya"), if at all, may go to someone else born truly in the named nakshatras!
With best regards,
Balachandra Rao

Sb: 27 Nakshatras
Dear Dr Balachandra Rao,
Sometime back, when this subject cropped up in BAS, Keerthi had given a list of the 27 Nakshatras and their English names. (Personally, I knew 2 of them; my wife’s and mine, as the priests ask them, as gate passes, when they perform archanas.) I had a benched programmer at that time and I asked her to make google searches and fill up additional columns, as titled by me. However, the work was stalled in a couple of days, as I could assign my company’s professional work to her.
The partly completed Table is given below. My personal request to you is to advice me on any additional columns which need to be included, so that when I retake the work, a more comprehensive Reference Table can be produced, with additional information.
There will be nothing original in the Table; it will be only a Structured Ready Reference Table, whose data is compiled from internet sources.
It was thousand to one coincidence: the programmer’s name is Revathi and much as she searched, she could not get a “Popular Name” for Revathi and (in lighter vein) is rather upset that she has to do with a fishy Other Name of ζ Piscium ! During our get together evening tea time (when we all talk freely with each other, without any inhibitions, from CMD to driver), she told me that she would trade 25% of her Java knowledge to any old sage, if he could give her a nice Other Name resembling and sounding like “Nunki or Shaula or even Bellatrix”.
With best wishes
Vasanth

The wikipedia article on 27 Nakshatras is very helpful also.

Hello doxinboy,
In a thread called "Sky Maps" Keerthi Kiran had shared some Indian star names.
This is the link he had shared:
http://www.findyourfate.com/indianastro/nakshatras.htm
You can as well google to find the entire list of what you seek. Just one example, however without English names.
http://www.mypanchang.com/nakshatras.html
Our senior scholar on the matter, Dr Balachandra Rao could shed more light on the matter. Thanks, Amar.
