‘Ring Of Fire’- Last Annular Solar Eclipse Of Decade Viewed from St Aloysius College

 Mangaluru: The Annular Solar Eclipse, the last one for the decade, began at around 8 am this morning and lasted till about 11.15 am. Often referred to as the “Ring of Fire”- the solar eclipse or “Surya grahan” was initially visible as a partial eclipse and was viewed first from Riyadh in Saudi Arabia. In India, the rare celestial spectacle was first viewed from Chervathur in Kerala. People from Karnataka and Tamil Nadu were also able to see the annular solar eclipse, while the rest of the country could see a partial solar eclipse.


As per sources, The annular solar eclipse was visible from 9:04 am (IST). The maximum eclipse was visible at around 10.47 am and the full eclipse was seen at the last location at the Pacific Ocean’s Guam at 12:30 pm (IST). In India, the maximum duration of the annular solar eclipse was just over 3 minutes. There are three types of solar eclipse – Total, Partial and Annular. Sources reveal that solar eclipse occurs when the Moon passes between Earth and the Sun, totally or partly obscuring the Sun for a viewer on Earth. An Annular Solar Eclipse takes place when the moon’s apparent diameter is smaller than that of the Sun’s, blocking most of the Sun’s light. This causes the Sun to look like a ‘ring of fire’.

Most years have two solar eclipses and in rare cases, there can be up to seven eclipses in a year. Partial phases of the solar eclipse was visible from various parts of the country in varying magnitude, depending on its geographical position. For the duration of the eclipse, many temples across the country were shut and will reopen after purification rituals, going by tradition. It is said several cultures and faiths believe that during an eclipse, the sun emits radiations that are negative and temples are kept shut so as to prevent these radiations from affecting the deity.

Ahead of the solar eclipse, astronomers issued a set of dos and don’ts for safe viewing. Sky watchers were advised to use safe viewing equipment and proper techniques to view the celestial event as the infrared and ultraviolet rays of the Sun can cause severe retinal damage. “One should not look at the Sun directly for even a little period without proper protection. Even when 99 per cent of the surface of the Sun is covered by the moon during partial eclipse, the remaining light is still intense enough to damage the eye. Proper solar filters with certified appropriate optical density against radiation which are safe to the eyes should be used in front optical devices and the naked eye,” said Dr T Chandra Shekara Shetty-Professor in the Physics Dept at St Aloysius College.

According to experts, the best way to view the solar eclipse is a pinhole camera or a telescopic projection used on a suitable surface. Besides India, the eclipse was visible in Saudi Arabia, Qatar, United Arab Emirates, Oman, Sri Lanka, Malaysia, Indonesia, Singapore, Northern Mariana Islands, and Guam. And here locally in Mangaluru, St Aloysius College (Autonomous), Mangaluru witnessed ‘Annular Solar Eclipse’ the biggest astronomical event of the year on 26th December 2019 in the college. Association of Friends of Astronomy, Goa also joined to facilitate the eclipse observation with telescopes and cameras. The solar eclipse stared at 8.03 am and Annular Eclipse occurred at 9.24 am. It was a memorable moment to all the viewers.

Dr J. J. Rawal , the President of Indian Planetary Society and Former Director Research & Director Nehru Planetarium Mumbai was also present. Fr Dionysius Vaz Sj -Rector of St Aloysius Institutions, Fr Praveen Martis Sj Principal of SAC, a large number of teachers, students, children and general public viewed the eclipse through various modes. The Physics department of St Aloysius College under the leadership of Professor Dr Chandra Shekara Shetty and Assistant Professor Shawn D’souza organised the event.
