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, Mar 25: In what is suspected to be the second COVID-19 death in Karnataka, a 70-year-old woman from Gouribidanuru, who was under house quarantine for the last one week has died at Rajiv Gandhi Hospital for Chest Diseases.

The woman, who had recently returned from the Mecca pilgrimage developed fever on Tuesday afternoon. She was rushed to hospital, where she died on Wednesday morning.

Health and Family Welfare officials said that the throat swab sample of the woman had been sent to the laboratory for testing and the result was expected to come by afternoon.

Since last week, at least three cases of COVID-19 positive had been reported in Gouribidanuru in Chikkaballpura district, about 80 kms from Bengaluru.

Most of the suspects and confirmed cases had returned from Makkah pilgrimage. Even the deceased woman was one of them and had been advised house quarantine.

On Tuesday morning, she developed fever and was shifted to Gouribidanur hospital and later to Chikkaballapura hospital. By evening, she was moved to Rajiv Gandhi hospital, where she died on Wednesday morning.

The Chikkaballapura district administration has proclaimed prohibitory orders in the locality. They have also taken the woman's family members for testing.

New Delhi, Jun 16: The class 10 and 12 students of the CICSE board can choose not to appear for pending board exams and be marked as per their performance in pre-board exams or internal assessment, according to top officials.

The board had also submitted the proposal before the Bombay High Court on Monday in response to a petition filed by a parent seeking directions to the authorities to cancel exams in view of the spike in COVID-19 cases.

According to Gerry Arathoon, Chief Executive and Secretary, Council for the Indian School Certificate Examinations (CISCE), the students will have to communicate their option to their respective schools by June 22.

The exams which were postponed due to the lockdown to contain the spread of coronavirus, are now scheduled to be conducted from July 1 to 14. However, several parents have been demanding the exams be scrapped.

"The students will be given two options---they either appear for the rescheduled exams or choose to have their results based on their performance in the pre-board exams or internal assessment. The option will be available only for the pending exams, the result of the subjects for which exams were already conducted, will be calculated as per performance in the exam only," Arathoon said.

The board also clarified that the students will not be entitled to make a subject-wise choice between the two options for pending exams.

Unlike the Central Board of Secondary Education (CBSE), which will only be conducting exams in 29 subjects crucial for promotion and admission to higher educational institutions, the CISCE will be conducting all pending exams.

The pending CBSE exams are scheduled from July 1 to 15. The schedule for the board exams has been decided in order to ensure that they are completed before competitive examinations. While the engineering entrance exam JEE-Mains is scheduled to be held from July 18 to 23, the medical entrance exam NEET is scheduled for July 26.

While the CBSE has given the option to not appear for pending board exams for differently-abled students, it has canceled the examinations for its around 250 schools situated abroad and has adopted the criteria of awarding marks on the basis of either practical exams conducted or the internal assessment marks.

A group of parents has filed a petition in the Supreme Court seeking a direction to the CBSE to declare results on the basis of tests already conducted, and calculate the total on an average basis with internal assessment marks of the remaining subjects.

Universities and schools across the country have been shut since March 16, when the Centre announced a countrywide classroom shut down as part of measures to contain the COVID-19 outbreak. A nationwide lockdown was announced on March 24, which came into effect the next day.

According to Home Ministry guidelines, there will be no exam centres in containment zones.

"Wearing of face masks by teachers, staff and students will be mandatory. There shall be provisions of thermal screening and sanitiser at the centres and social distancing rules will have to be followed at exam centres. Special buses may be arranged by states and UTs for transportation of students to exam centres," the Home Ministry has said.
