Actor Rahul Roy joins BJP

Washington, Apr 23: Air pollution over northern India has plummeted to a 20-year-low for this time of the year, according to satellite data published by US space agency National Aeronautics and Space Administration (NASA).
The US space agency's satellite sensors observed aerosol levels at a 20-year low post the countrywide lockdown, implemented to slow the spread of the novel coronavirus.

"We knew we would see changes in atmospheric composition in many places during the lockdown," said Pawan Gupta, a Universities Space Research Association (USRA) scientist at NASA''s Marshall Space Flight Center. "But I have never seen aerosol values so low in the Indo-Gangetic Plain at this time of year," added Mr Gupta.

Acting Assistant Secretary of State for South and Central Asia Alice G Wells tweeted, "These images from NASA were taken each spring starting in 2016 and show a 20-year low in airborne particle levels over India. When India and the world are ready to work and travel again, let's not forget that collaborative action can result in cleaner air."

The data published with maps show aerosol optical depth (AOD) in 2020 compared to the average for 2016-2019. Aerosol optical depth is a measure of how light is absorbed or reflected by airborne particles as it travels through the atmosphere.

If aerosols are concentrated near the surface, an optical depth of 1 or above indicates very hazy conditions. An optical depth, or thickness, of less than 0.1 over the entire atmospheric vertical column is considered "clean." The data were retrieved by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite.

In the first few days of the lockdown, it was difficult to observe a change in the pollution signature. "We saw an aerosol decrease in the first week of the shutdown, but that was due to a combination of rain and the lockdown," said Mr Gupta.

Around March 27, heavy rain poured over vast areas of northern India and helped clear the air of aerosols. Aerosol concentrations usually increase again after such heavy precipitation.

"After the rainfall, I was really impressed that aerosol levels did not go up and return to normal. We saw a gradual decrease and things have been staying at the level we might expect without anthropogenic emissions," Mr Gupta said.

On March 25, the Indian government placed its 1.3 billion citizens under a strict lockdown to reduce the spread of COVID-19. The countrywide mandate decreased activity at factories and severely reduced car, bus, truck and airplane traffic. Every year, aerosols from anthropogenic (human-made) sources contribute to unhealthy levels of air pollution in many Indian cities.

Aerosols are tiny solid and liquid particles suspended in the air that reduce visibility and can damage the human lungs and heart.

In southern India though, the story is a little hazier. Satellite data show aerosol levels have not yet decreased to the same extent. In fact, levels seem to be slightly higher than in the past four years. The reasons are unclear but could be related to recent weather patterns, agricultural fires, winds or other factors.

"This a model scientific experiment," Robert Levy, program leader for NASA's MODIS aerosol products, said about the lockdown and its effects on pollution.

"We have a unique opportunity to learn how the atmosphere reacts to sharp and sudden reductions in emissions from certain sectors. This can help us separate how natural and human sources of aerosols affect the atmosphere," Mr Levy added.

New Delhi, Jun 20: A rare celestial event, annular solar eclipse, which is popularly known as the "ring of fire" eclipse, will be visible this Sunday in India.

It will be the first solar eclipse of this year takes place on the summer solstice, which is the longest day in the Northern Hemisphere.

While people living along the path annular eclipse passing through Anupgarh, Suratgarh, Sirsa, Jakhal, Kurukshetra, Yamunanagar, Dehradun, Tapowan and Joshimath will be able to see the annular phase, people in rest of India can witness a partial eclipse, said the Ministry of Science and Technology.

When Moon comes between the Sun and Earth, the shadow falls on the surface of the Earth. The Sun is entirely covered by the Moon for a brief period. Those places that are engulfed by the dark, dense umbral shadow of the Moon experience the total solar eclipse. In the regions that plunge into the soft diffused penumbral shadow of the Moon experience the partial eclipse.

"Annular solar eclipse is a particular case of the total solar eclipse. Like the total solar eclipse, the Moon is aligned with the Sun. However, on that day, the apparent size of the Moon happens to be a wee smaller than the Sun. Hence the Moon covers the central part of the Sun, and the rim of the Sun appear like a 'ring of fire' in the sky for a very brief moment" explains Samir Dhurde of The Inter-University Centre for Astronomy and Astrophysics, Pune.

During the solar eclipse, the apparent size of the Moon is smaller than that of the Sun by 1 per cent, the expert said.

Allying rumours that the eclipse will mark the end of coronavirus, Aniket Sule, Chairperson, Public Outreach and Education Committee of the Astronomical Society of India, said: "Solar eclipse is caused when the Moon comes in front of the Sun for a short time. As seen from Earth eclipses occur somewhere in the Earth 2 to 5 times a year. Eclipses do not impact microorganisms on Earth. Likewise there no danger in eating of stepping out during an eclipse. No mysterious rays come out of the Sun during an eclipse."

New Delhi, Apr 28: Outstanding loans amounting to Rs 68,607 crore of top 50 wilful bank loan defaulters in the country including firms of Mehul Choksi and Vijay Mallya have been technically written off till September 30, 2019, the Reserve Bank of India said in a RTI reply.

Absconding dimantaire Choksi's company Gitanjali Gems tops the list of these defaulters with a whopping amount of Rs 5,492 crore, according to the list.

This is followed by REI Agro with Rs 4,314 crore and Winsome Diamonds with Rs 4,076 crore.

Rotomac Global Private Limited has funded advances of Rs 2,850 crore which have been technically written off and Kudos Chemie Ltd with Rs 2,326 crore, Ruchi Soya Industries Limited, now owned by Ramdev's Patanjali, with Rs 2,212 crore and Zoom Developers Pvt Ltd with Rs 2,012 crore being the other companies.

Mallya's Kingfisher Airlines figures in the list at number 9, with outstanding of Rs 1943 crore which have been technically written off by the banks.

Forever Precious Jewellery and Diamonds Private Limited has loans of Rs 1,962 crore written off while Deccan Chronicle Holdings Limited have Rs 1915 crore written off loans.

Choksi's other firms Gili India and Nakshatra Brands also have loans of Rs 1,447 and Rs 1109 crore respectively written off.

REI Agro of Jhunjhunwala brothers is already under the scanner of ED. The CBI and ED are also probing alleged fraud by the owners of Winsome Diamonds.

Vikram Kothari's Rotomac is the fourth in the list. He and his son Rahul Kothari were arrested by the CBI for bank loan default.

In the last Parliament session, Rahul Gandhi had asked the government to provide a list of top 50 bank loans defaulters in the country, leading to sharp exchanges and uproar in the Lok Sabha.

"The information on top 50 wilful defaulters and their sum of funded amount outstanding and amount technically/prudentially written off as on September 30, 2019 reported in CRILC by banks, is provided," the RBI said in its written response dated April 24.

In his application, RTI activist Saket Gokhale had sought the list of defaulters as on February 16, but the RBI said the requested information is not available.

The RBI said that according to section 8 (1)(a) of RTI Act 2005 read with para 77 of Supreme Court judgement of December 16, 2015 in Jayantilal N Mistry case, information on overseas borrowers is exempted from public disclosure.

"Data is as reported by banks and RBI will not be held responsibly or accountable for any misreporting and/or incorrect reporting by the reporting entities," the RBI said in the written reply to the RTI query.
