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.

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.

Mangaluru/Mysuru, May 19: Though the Karnataka government permitted the private buses, operators in Dakshina Kannada district have decided not to operate buses until May end. In Mysuru district too the private buses remained off the roads.

Dakshina Kannada Bus Owners’ Association President Dilraj Alva said “Technically, private bus operators are not able to operate services as all of us have surrendered our permits. If we start services we will have to pay the tax for entire month. Hence, we have decided to resume bus services from June 1.”

The private buses had suspended their services since March 24.

In addition, bus owners also have two more demands which the state government needs to consider on priority, he said.

“We have requested the government to exempt private buses from paying tax for the next six months. We were not plying buses during lockdown and it will be tough for us in the next three months to operate as per new conditions.”

“The government has allowed only 30 persons in each bus to maintain social distancing. In addition, we have been urging the state government for bus fare revision since 2013. The government has revised the bus fares of KSRTC twice after that,” Alva said adding that bus owners will be meeting Mangaluru RTO on Tuesday.
