India will witness its “deepest” annular

solar eclipse

of this century this Sunday (June 21), with the Sun appearing as a necklace of pearls for around 30 seconds during the maximum phase along a narrow corridor running through Rajasthan, Haryana and Uttarakhand.
The eclipse will be partial in the rest of the country, report Amit Bhattacharya & Vishwa Mohan. An annular solar eclipse occurs when the apparent size of the


is slightly less than that of the Sun, which leaves the outer rim of the latter uncovered, giving the appearance of a “ring of fire”.
During this eclipse, that ring is expected to be very thin as the Moon will cover up to 98.8% of the solar disc, making it the “deepest” annular eclipse of the century in India, according to experts. “Instead of a wide fiery ring, the Sun may appear as a necklace of shiny beads (known as Baily’s beads) due to light filtering through Moon’s hills and valleys,” said astro-photographer Ajay Talwar.
There’s a possibility that the Sun’s corona, an ethereal halo around the solar disc, will be visible during this eclipse. With the next eclipse (visible from the country) 11 years away in 2031, this is a big astronomical event for India. Many global eclipse chasers were expected to watch it from India but the Covid-19 pandemic dashed those plans. Domestic travel curbs have dampened the plans of many Indian enthusiasts as well.
Astro-photographer Ajay Talwar had initially planned to document the event from a high-altitude meadow near Auli in Uttarakhand. He is now headed to Sirsa, in Haryana, since it doesn’t entail crossing any state borders from his Gurgaon home.
Sneha Kesari, who runs a firm devoted to


, had planned to take international eclipse buffs to Tibet’s Mansarovar lake for the event. “Celebrated eclipse chaser Xavier Jubier was coming too, but then the trip had to be cancelled,” said Kesari.
The prominent places within the narrow central path of the eclipse are Dehradun, Kurukshetra, Chamoli, Joshimath, Sirsa and Suratgarh. The partial eclipse will be visible in India from different places at different timings between 9.56am and 2.28 pm. In Delhi, the eclipse will begin at 10.19am and end at 1.48pm, with the maximum phase occurring at 12.01pm. Issuing advisories, the the ministry of earth sciences said, “The eclipsed Sun should not be viewed with the naked eye, even for a very short time. It will cause permanent damage of the eyes leading to blindness.”
