Sharjah Expo: Shanti Prakashana’s 4th year of participation

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.

Newsroom, May 2: The Delhi Police’s move to book Delhi Minorities Commission chairman Zafarul Islam Khan under sedition charges over his social media statement condemning Hindutva bigots has raised many eyebrows. 

A pubic statement has been issued in solidarity with Zafarul Islam Khan by a group of NGOs and citizens which condemned the media trial targeting Khan.

The statement demanded legal action against those who are distorting Khan's Facebook post and spreading false propaganda against him.

Delhi Police Special Cell registered the FIR against Khan on the complaint of a Vasant Kunj resident. The complaint came to the Lodhi Colony office of the special cell, after the assistant commissioner of police (ACP) Safdarjung Enclave forwarded it.

The investigation has been handed over to special cell inspector Praveen Kumar.

According to the FIR, Khan has been booked under several sections of the Indian Penal Code -- 124 A (sedition) and 153 A (Promoting enmity between different groups on grounds of religion, race, place of birth, residence, language, etc,).

Khan on April 28 had posted controversial comments on his Facebook page. "Mind you, bigots, Indian Muslims have opted until now not to complain to the Arab and Muslim world about your hate campaigns and lynchings and riots. The day they are pushed to do that, bigots will face an avalanche," Khan had written on Facebook.

However, the Delhi Minorities Commission's chief on Friday had apologised for his controversial remark and had said that he never tried to tarnish the image of India. He also removed the controversial post from the social media and issued a prolonged clarification.

Jan 2: A year after 12,000 acres of forests in Bandipur went up in smoke, the Karnataka Forest Department is gearing up for the summer even as the Forest Survey of India (FSI) has cautioned that 22.78 lakh acres (9,222 sq km) or about 20% of the green cover spread across three districts in the central part of the state is fire-prone.

The FSI studied forest fire incidents across the country between 2004-05 and 2017 before coming up with state-specific inputs.

According to the 13-year observation, Karnataka has 7,352 “fire points” or areas measuring 5 km X 5 km with frequent fire incidents.

Though the number is lower compared to states like Maharashtra, Madhya Pradesh and Odisha with over 20,000 points, the sheer spread of the fire-prone area itself is a challenge for the Karnataka Forest Department.

According to data, about three lakh acres (1,199.9 sq km) of forest area is very highly fire prone with 26 to 52 fire incidents in 13 years. This is followed by 7.6 lakh acres (3,067 sq km) of “highly fire prone” areas with an average of one to two incidents every year.

Almost all of the “red alert” areas are concentrated in Uttara Kannada, Chikkmagaluru, Shivamogga and Chamarajanagar districts. As temperature rises at the end of January, so does the risk of forest fires, requiring officials to be on vigil till the end of summer.

After an investigation into the Bandipur blaze revealed that faulty fire lines and poor supervision were the reason for the spread of the fire, the department has come up with a multi-pronged approach to prevent similar incidents this year.

“After the Bandipur incident, we have created a fire cell and a standard operating procedure (SOP) which everyone has to follow. Firstly, a fire management plan is prepared and approved by a competent authority.

The SOP has well defined firelines which have to be executed by December-end and burning must be completed by January 15,”  Principal Chief Conservator of Forests (Head of Forest Force) Punati Sridhar told DH.

He said that to ensure its strict implementation, GPS readings of firelines are to be submitted for random verification.

“All the required equipment from fire jackets to shoes, gloves, backpack sprayers and tractors mounted with 2,000-5,000 litre tanks with high pressure pumps will be deployed at vantage points,” he said.

In addition, the department’s fire cell works in collaboration with the Karnataka State Remote Sensing Applications Centre (KSRSAC) to give fire alerts within half and hour of an area catching fire and detected by satellites.

“Earlier, the gap used to be four hours by when the fire would have spread beyond control. Now, with reduced time gap, it would be easier to control fire early,” he added.
