NEW DELHI: An annular
(forming ring of fire in the sky), occurring on June 21, will be visible from some places within a narrow corridor of northern part of the country — parts of Rajasthan, Haryana and
— for over 30 seconds. It’ll, however, be seen as partial solar eclipse from the rest part of India for over 3 minutes on that day.
The prominent places within this narrow annularity path are
, Kurukshetra, Chamoli, Joshimath, Sirsa and Suratgarh. The annular solar eclipse will be seen at different timings from these places between 11.52 am (IST) and 12.09 pm (IST), ranging from 31 seconds to 45 seconds, on June 21.
A solar eclipse occurs on a new moon day when the Moon comes in between the Earth and the Sun and when all the three objects are aligned. An annular solar eclipse occurs when the angular diameter of the Moon falls short of that of the Sun so that it cannot cover up the latter completely. As a result a ring of the Sun’s disk remains visible around the Moon.
Globally (considering the Earth as a whole), the
of the eclipse will begin at 9.16 am (IST) and end at 3.04 pm (IST). The annular phase will, however, begin at 10.19 am (IST) and end at 2.02 pm (IST).
The partial eclipse will be visible in India from different places at different timings between 9.56 am (IST) and 2.28 pm (IST) for little over 3 minutes.
Announcing the timing and phases of eclipse,
the ministry of earth sciences
(MoES) on Tuesday said, “In India, the obscuration of the Sun by the Moon at the time of greatest phase of the annular eclipse will be nearly 98.6%.”
On partial eclipse, it said, “Obscuration of the Sun by the Moon at the time of greatest phase of partial eclipse will be around 94% in Delhi, 80% in Guwahati, 78% in Patna, 75% in Silchar, 66% in Kolkata, 62% in Mumbai, 37% in Bangalore, 34% in Chennai and 28% in Port Blair.”
Globally, the annular path will pass through Congo, Sudan, Ethiopia, Yemen, Saudi Arabia, Oman, Pakistan, northern parts of India and China.
Issuing an advisories including dos and don’ts for people who would like to watch the solar eclipse, the MoES said, “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 even when the moon covers most portion of the Sun.”
It said, “The safe technique to observe the solar eclipse is either by using proper filter like aluminized Mylar, black polymer, welding glass of shade number 14 or by making projection of Sun’s image on a white board by telescope.”
