'Ring of Fire' solar eclipse watchers should use safe viewing equipment on Dec 26: Debiprosad Duari
Kolkata, Dec 25: When the annular solar eclipse takes place on December 26, sky watchers should 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, a senior astronomer has said.
A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the Sun for a viewer on Earth.
An annular solar eclipse takes place when the moons apparent diameter is smaller than that of the Suns and blocks most of the Suns light. This causes the Sun to look like an ring (annulus) of fire, Debiprosad Duari, the Director, Research and Academic of MP Birla Institute of Fundamental Research, MP Birla Planetarium, said.
Partial phases of the solar eclipse will be visible from all over the country in varying magnitude depending upon the geographical position.
One should not look directly to the Sun 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, Duari told PTI.
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, he said.
Aluminised mylar films of approved thickness and transmissivity coated with black polymer are the safest for use in solar goggles that one generally uses for eclipse viewing, he said.
Welders glass number 14 is a safe material as solar filter for direct viewing of the solar disc, the researcher said.
According to him, the best method to view the solar eclipse will be to use a pinhole camera or a telescopic projection on a suitable surface.
Use of unsafe filters like smoked glass, polarising filter, sun glasses, photographic neutral density filters, colour films are not advised to view the solar phenomenon, he said.
Thursday's eclipse will be visible in Saudi Arabia, Qatar, United Arab Emirates, Oman, India, Sri Lanka, Malaysia, Indonesia, Singapore, Northern Mariana Islands, and Guam.
Population centers in the path of the annularity include Udhagamandalam, Kozhikode, Coimbatore, Jaffna, Trincomalee, Singapore, Singkawang and Guam, Duari said.
In the Indian sub-continent, the annularity phases will be seen within a narrow path grazing the southern Indian peninsula through Karnataka, Kerala and Tamil Nadu before crossing the Bay of Bengal for northern Sri Lanka.
The people of the southern part of the country will be fortunate to see a greater part of the partial solar eclipse because of the geometry of the eclipse path. But every Indian will get an opportunity to see at least a partial eclipse. In India the maximum duration of the annularity phases will be just over 3 minutes, he said.
The beginning of the eclipse can be first seen from the Arabian sea coast of Oman at around 7:59 hours IST and the annular eclipse will become first visible in west of Bahrain at 09:06 hours IST, Duari added.

Karnataka Milk Federation enters Delhi-NCR, offers competitive pricing on Nandini products
New Delhi, Nov 21: Karnataka Chief Minister Siddaramaiah on Thursday launched the Karnataka Milk Federation's (KMF) Nandini brand milk products in the Delhi-NCR market, pricing them marginally lower than competitors to gain a foothold in the region.
The cooperative will retail four cow milk variants, curd, and buttermilk from Friday, with competitive pricing that undercuts established players like Mother Dairy and Amul.
Cow milk will be sold at Rs 56 per litre, full Cream Milk at Rs 67 per litre, Standardised Milk at Rs 61 per litre, Toned Milk at Rs 55 per litre, and curd at Rs 74 per kg.
"We have surplus milk in the state. KMF along with Mandya Milk Union will market surplus milk of 3-4 lakh litres per day in Delhi-NCR," Siddaramaiah told reporters after launching the products.
The federation currently collects 100 lakh litres of milk daily, with local consumption at 60 lakh litres, leaving a surplus of 40 lakh litres for expansion into new markets.
However, the Chief Minister acknowledged the challenges of transporting milk over 2,500 km, which takes 50-54 hours.
There is a need to find new markets for surplus milk and gradually the KMF should be able to sell 5-6 lakh litres per day in Delhi-NCR, he added.
KMF Chairman LBP Bheemanaik assured that milk quality would be maintained during transit.
The federation has already partnered with 40 dealers in the Delhi-NCR region to facilitate sales, he added.
With a robust infrastructure of 26.76 lakh milk producers, 15,737 dairy cooperative societies, and 15 district milk unions, KMF has a turnover of Rs 25,000 crore and exports dairy products to over 25 countries.
State Animal Husbandry Minister K Venkatesh and Agriculture Minister N Cheluvarayaswamy were present at the product launch.
