Many years ago, on an experience to Mumbai to fulfill my father, we have been talking about an imminent solar eclipse and whether I could view it in Delhi. He straight away took out a bit ebook, looked at some charts in it, and said, “Not overall; however, you’ll have the ability to look at a few.” He gave me its approximate time and also told me approximately two planets that would be seen in the close to destiny.
The thin one hundred eighty-page e-books became a periodical called Lahiri’s Indian Ephemeris of Planets’ Positions. Earlier this month, I changed into checking out his books and, among them, determined that replica, a 2008 edition.
An ephemeris is a journal that gives the location of astronomical gadgets in the sky in the course of the path of the 12 months. It is used by each astronomer and astrologer—for different functions. The query, but, is in this day and age, while facts are ready to be had online, what use is a published ephemeris?
Out of interest, I offered the ultra-modern version (Amazon, Rs160), and, tons to my marvel, located a wealth of data—on phases of the moon, eclipses, daily motion of planets, sunrise and sunset, and equinoxes and solstices.
I am familiar with some of the common clinical phrases. Still, there is data in it approximately various forms of time and calendars that I didn’t realize a lot about: For example, there are charts on sidereal time, used by astronomers to place their telescopes. A sidereal day is around four minutes shorter than our 24-hour day based on solar time. It is measured via the Earth’s rotation relative to that of stars.
Long lower back, several Indian towns kept their own local time. There was Calcutta time and Bombay time. When the British set up railways in India, they delivered Madras Time as the standard because town is halfway between Calcutta and Bombay. Madras Time also became known as Railway Time because it changed into observed via railways across u. S. A. But the history of popular time in India is a distinct story.
Astronomy aside, the ephemeris is also a handbook for astrologers: There are all kinds of statistics on nakshatra (constellations), a tithi (date), yoga (auspicious moment), the signs of the zodiac, the position of the planets on the subject of these signs and symptoms, a desk of “ascendants” (your “growing signal”) and loads more than I do now not apprehend (my translations are from Wikipedia).
In historical times, astronomy and astrology have been carefully linked. But they’re two separate disciplines. Mylene Perez, an astrophysicist, explains the distinction pretty honestly in a YouTube video: Astronomy is considered technological know-how; it’s the study of all celestial bodies in the universe. Astrology is a notion that everything in space has a right away correlation to human events.
It depends on what you’re seeking out in an ephemeris. There are exciting astronomical facts that a layperson with an informal interest in the problem can use. If you are into astrology and agree with your stars and such matters, there’s also lots for you in it. But to decipher that, you will need an expert astrologer.
My father becomes a person of technology; his interest inside the ephemeris become astronomical statistics. The statistics he located in the book also became available online. However, he didn’t recognize how to use a laptop. And this is wherein the printed ephemeris is available, and why he would buy it yr after year, long before computers arrived.
The guy who began printing the ephemeris some 80 years ago, Nirmal Chandra Lahiri, was a Paris-based International Astronomical Union member. His grandson Suparna Lahiri, who now compiles the ephemeris, told me that the book is largely about astronomy but is likewise popular amongst astrologers as “they can convert the records to their use.” For example, it has correct statistics on sundown and sunrise, planetary positions based on astronomical models, and the sidereal time calculations, all of which astrologers require to make predictions.
Today, there are various websites wherein these records—astronomical in addition to astrological—are to be had. You can download the Indian astronomical ephemeris without cost from the government of India’s Positional Astronomy Centre website. It’s quite a comprehensive website and has records for people with an informal hobby within the issue and specialists.
So what then explains the recognition of the printed ephemeris, together with Lahiri’s, which is now into its eightieth version? One, it’s a handy manual for folks that can’t use computer systems, and two, it’s a handy compendium of information in one vicinity.
You shouldn’t trawl the internet or consult a pandit to discover when Diwali is. It’s on 7 November, and this is as correct as it could get. And if you are inquisitive about astronomical occasions, there’ll be a total lunar eclipse on 27 July, and it’ll be visible throughout India.
