‘UB City assault victim is not BJP worker’: Amit Shah admits his blunder

Mangaluru, Apr 23: An astronomical phenomenon, ‘Zero Shadow Day', will be observed in Mangaluru on April 24 and in Udupi on April 25. 

According to a press release from Poornaprajna Amateur Astronomers’ Club, the wonder will commence and people will see their shadows disappear for a few moments at 12:28 pm.

The phenomenon is called as Zero Shadow Day. If a person takes a candle in a dark room and use it to create a shadow of one’s palm on the wall, the hand will cast shadow on the wall as one moves the hand. But when one places the palm on the wall, there will be no shadow.

In the phenomenon, the sun at these times shines exactly above the heads on these days. In astronomy, this point is called as Zenith. The point in the sky directly above an observer at any given location. So it is quite clear now that on Zero Shadow Day, the sun passes through the Zenith as a result of which, all objects will have minimal or no shadow if they are on the ground.

The reason for this happens on some specific days is concerned with astronomy. The earth spins around on its own axis and causes days and nights. It also revolves around the sun causing a year. But the seasons are caused because the axis is tilted at an angle of 23.5 degrees. It is because of this tilt that the sun rises every day in the east gradually moving towards the north till June 21st and then slowly proceeding towards the south till December 21st every year. “We call these days solstice. This means the sun shines between the Tropic of Cancer and Tropic of Capricorn every day passing by the equator on the days we call equinox,” the release stated.

As the earth moves around the sun and revolves on its own axis, for all the people between Tropic of Cancer and Tropic of Capricorn, the Sun at noon moves father and closer to the zenith passing through zenith twice causing two Zero Shadow Days per year. People at Mangaluru will observe this on April 24 and August 18 every year and People in Udupi will observe this on April 25 and August 17 every year.

Places with same latitudes will observe the same days of Zero Shadow but the time would vary with longitude. For example, people of Bengaluru as they share the latitude with Mangaluru will also observe it on April 24. While the people of Mangaluru will observe their shadows disappear at 12.28pm, people of Bengaluru will observe this at 12:17pm. Places like Moodabidri, Bantwal, Sakleshpur and Hassan will also observe Zero Shadow on April 24.

Places like Brahmavar, Karkala, Sringeri, Kudremukha, Chikkamagaluru will observe the Zero Shadow Day on the same day as Udupi on April 25.

Bengaluru, Feb 23: Bolstered by the Supreme Court's interim nod for the gazette notification of the Mahadayi Water Dispute Tribunal award by the Central government, Karnataka decided to allot funds for the drinking water project in the state's northwest region, an official said on Saturday.

"Funds will be allotted in the state budget for fiscal 2020-21 to complete the Kalasa-Banduri project across the Mahadayi river for supplying drinking water to the four drought-prone northern districts in the state," the official of the water resources department told media on anonymity.

As Chief Minister B.S. Yediyurappa also holds the finance portfolio, he has agreed to allocate funds for the project, held up for years in the legal battle with the neighbouring Goa and Maharashtra over the sharing of the river water among the three coastal states.

Yediyurappa is slated to present the state budget for the ensuing fiscal in the legislative assembly on March 2.

"We will resume the project work once the Centre notifies the award though it will be binding on the final outcome of the apex court's hearing the review petitions of Goa and Maharashtra against the Tribunal award," the official noted.

A division bench of Justice D.Y. Chandrachud and Justice Hemant Gupta on Thursday passed an interim order on the Tribunal award, allowing the central water resources ministry to notify it for implementation and posted the case for final hearing in July.

The Tribunal on August 14, 2018 allocated 13.42 thousand million cubic feet (tmcft) of the river water to the southern state for irrigation and drinking water supply to towns and villages across Bagalkot, Belagavi, Dharwad and Gadag districts, which are in the arid region of the Deccan plateau.

The four districts are about 400-550 km northwest of Bengaluru in the southern state.

Of the 13.42 tmcft water, 5.5 tmcft will be used in the river basin and for diversion into the depleted Malaprabha reservoir while the balance 7.92 tmcft will be utilized for hydel power generation instead of allowing the water to go into the Arabian Sea on the state's west coast through Goa.

Goa, which opposed Karnataka's demand for 36.66 tmcft, was allocated 24 tmcft, while Maharashtra got 1.3 tmcft.

The Tribunal assessed that 188.06 tmc feet water is available at 75 per cent dependability.

The three-member Tribunal is headed by Chairman Justice J.M. Panchal, Justice Viney Mittal and Justice P.S. Naayana.

The Union government had set up the inter-state Tribunal on November 16, 2010 for the djudication of the Mahadayi basin water allocation among the three riparian and contiguous states.

Goa and Maharashtra claimed 122.6 tmc feet and 6.35 tmc feet of the river water respectively.

The Tribunal, which commenced sittings on September 6, 2012, held 1,209 sittings for over 6 years.

Supreme Court senior counsel F.S. Nariman represented the state before the Tribunal to present its case.

The Tribunal's chairman and two members inspected the river basin area across the three coastal states from December 12-24, 2013.

The 77km-long Mahadayi or Mandovi river originates at Bhimgad in the Western Ghats in Belagavi district and flows into the neighbouring Goa through Maharashtra and joins the Arabian Sea off the west coast.

Though the river flows 29 km in Karnataka and 52 km in Goa, its catchment area is spread over 2,032 km in the southern state as against 1,580 km in the western state (Goa).
