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 24: Census authorities in Karnataka have requested deputy commissioners in the state’s districts to hold outreach and awareness campaigns about the National Population Register (NPR), as they fear misgivings about the exercise could hurt the forthcoming enumeration of population.

The house-listing phase of the Census and updating of NPR will be rolled out simultaneously by mid-April in the BJP-ruled state.

About 1,50,000 enumerators will handle the massive exercise.

Officials believe widespread awareness will help address concerns about the NPR data-gathering process and make people cooperate with enumerators when they visit houses for both NPR and census work.

“Sensing the kind of questions that enumerators may face when they do house visits, in all video conferences with deputy commissioners of districts, we have requested to establish contact with local representatives,” SB Vijay Kumar, director of Census Operations in Karnataka told news agency. “We have asked them to organise outreach programmes to ensure that people’s doubts are resolved before the information gathering work begins,” he added.

Census operations are handled by the Union home ministry. Several district officials are said to have raised concerns about the possibility of people refusing to share information when the work on the census and NPR begins in two months. This would affect the quality of the census work, making the exercise incomplete.

news channel earlier reported that people in parts of Karnataka had declined to share personal information with officials visiting households in connection with government programmes, suspecting them of gathering data for the yet-to-be unveiled National Register of Citizens, following enactment of the Citizenship Amendment Act (CAA) recently.

Kumar said district authorities will train and sensitise enumerators to tread carefully while gathering information. Enumerators will be told not to demand information but seek it gently.

“We will tell enumerators to proactively engage with people. For instance, if an old man in a village does not know his exact date or place of birth, the enumerator may engage in a conversation with the person that may elicit some anecdotes and roughly establish the year and the place of birth,” the census director said.

As of now, the NPR questionnaire has 21queries, but officials say it has not yet been finalised.

With most of the census and NPR data gathering and storage happening digitally this time, the challenge before census officials is to convince people that the data would remain safe.

“Individual data is sealed and all that we can see is collective data. The information is consolidated and tailor-made. We are telling district officials to create awareness about data safety as well,” Kumar said.

Hubli, May 2: Around 1400 migrant workers from neighbouring districts, working at brick manufacturing factories in Hubli were sent to their respective districts on buses, amid coronavirus lockdown on Friday.

Dr Purushottam, Nodal Officer, COVID-19 task force said, "Total 1473 labourers from eight neighbouring districts, working in the brick manufacturing units of our district were sent by 74 buses. 876 labourers are from Kalburgi where we are sending 44 buses, 350 labourers are from Vijaypura where we are sending 27 buses."

He continued saying that 20 persons will be accommodated in a bus while maintaining social distancing.

"Before the labourers boarded, the buses were disinfected. NWKRTC officials took a special interest in doing so. The District Collector has written letters to the concerned DCs regarding shifting of labourers in every bus, one Nodal Officer will handover them to the local officials," Dr Purushottam added.

On Friday, the buses were sent to seven districts and one bus will be sent today.
