Surya Grahan 2027: 2 August 2027

The solar eclipse of Monday, 2 August 2027, comes on the day of Shravana Amavasya. It is total along a narrow path and greatest in southern Egypt at 15:37 IST; in the ten cities on this site it is a partial eclipse in the late afternoon, beginning first in Ahmedabad at 15:45 and ending last in Bengaluru at 17:43. The table gives each city's times, how much of the Sun is covered and when the traditional sutak begins.

Times in ten cities

Indian Standard Time, to the nearest minute, for each city centre. Sun covered is the share of the Sun's disc hidden at greatest eclipse. Sutak from is 12 hours before the eclipse begins there, by the traditional rule; it ends when the eclipse ends.

What India sees

The Moon takes its first bite from the Sun's edge in the mid-afternoon and leaves it before sunset everywhere in the table, so the whole eclipse is in the sky. In general, the farther south and west the city, the more of the Sun is covered: about 39% in Bengaluru, about 8% in New Delhi and about 6% in Kolkata. Even the deepest phase leaves most of the Sun uncovered, so daylight barely changes; the eclipse is noticed through a proper filter rather than by the light.

At greatest eclipse the Sun and the Moon stand together in Cancer, in Pushya nakshatra (sidereal, Lahiri ayanamsa), close to Ketu, which holds Cancer through 2027; a new moon that near a node is what allows the eclipse.

Sutak for the solar eclipse

Sutak is the traditional interval before an eclipse in which temple worship and ordinary cooking are set aside. Panchangs reckon it as four prahars, about 12 hours, before a solar eclipse begins and three prahars, about 9 hours, before a lunar eclipse begins, and it ends with the eclipse. It applies only where the eclipse can be seen. By the usual panchang convention a penumbral (upachhaya) lunar eclipse, in which the Moon never enters the Earth's dark inner shadow, is not counted as a grahan, so no sutak is reckoned for it.

For 2 August 2027 that puts the start of sutak in the early hours of the same day, from 03:45 in Ahmedabad to 04:14 in Kolkata, as the table shows; it ends when the eclipse ends in the afternoon. The times follow each city's own start of the eclipse, so a town near one of these cities is usually within a few minutes of it.

Watching it safely

Never look straight at the Sun during a partial eclipse, even when much of it is covered, and never through binoculars, a telescope or a phone camera without a solar filter in front of the lens. Use eclipse glasses or viewers that meet the ISO 12312-2 standard, or project the Sun's image through a pinhole onto a white card; sunglasses and smoked glass are not safe.

Reading the times

Begins is the moment the Moon's edge first touches the Sun's; greatest is the moment the largest share of the Sun is covered; ends is the moment the Moon's edge leaves it. All times are Indian Standard Time, rounded to the minute, for the city centre. The share of the Sun covered is by area, not by diameter, so a figure of a third means a third of the bright disc is hidden.

The times come from a careful calculation of the Sun and Moon for each city, checked against an independent calculation to within a minute; where the two fall either side of a minute, the table shows the earlier minute for a start and the later for an end. For a place not listed, the nearest city is a fair guide; the edges of the eclipse move by a few minutes over a few hundred kilometres.
