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.

New Delhi, Jun 8: Two civil defence employees have been arrested by the Rajasthan Police today in Jaipur based on Military Intelligence (MI) inputs that they had been passing on sensitive information to Pakistan's spy agency ISI.

The arrested are: Vikas Kumar (29), a civil defence employee at an army ammunition depot near Shri Ganganagar (Rajasthan) and Chiman Lal (22), a civil contractual employee of the army's Mahajan Field Firing Range (MFFR), Bikaner. 

Both were working as espionage agents on behalf of Pakistan's intelligence agency and were giving out details of Ammunition and MFFR, vital military installations in India's Western front. 

The MI Lucknow's operation named Desert Chase assumes great importance as the Shri Ganganagar Ammunition Depot and Bikaner MMFR are strategically important military installations on the western front along the Pakistan border.

The work on the "operation" began in August 2019, when the MI Lucknow, through its sleuths, learnt about an espionage agent near Sri Ganganagar who was passing military information to his handlers in Pakistan. The individual was identified as Vikas Kumar - the civil defence employee at an army ammunition depot near Sri Ganganagar.

The MI Lucknow shared the case with UP ATS in the month of January 2020. Vikas's activities were monitored and analysed by a joint team of MI Lucknow and UP ATS. The operation was code-named 'Desert Chase'.

Based on these, it was learnt that Vikas is acquiring photos of a "water distribution register" at a water point/pump house in MFFR through a contractual civil employee named Chiman Lal. The development of the case was halted due to the start of the lockdown period all across the country.

Finally, the case shared with Rajasthan Police Intelligence in the first week of May 2020. A joint team was formed between Rajasthan Police-Intelligence and MI Lucknow.

Fresh leads were found as new payments were detected along with a trail of sensitive information being passed on to Pakistan by two accused.  

Vikas Kumar confessed to having passed the following information to Pakistan:

•    Details received from Chiman Lal about Army units and their strength coming to MFFR.
•    Details of ammunition coming to his ammunition depot including their type, quantity, mode of transportation, date of arrival on a routine basis (almost every time it came to his notice).
•    Details of ammunition (to include their type, quantity and mode/date of transportation) further distributed/transferred to local army establishments/units (including two local brigades) and elsewhere from his ammunition depot.
•    ORBAT (Order of battle; composition related details) of two local army brigades and all changes in them as they came to his notice.
•    Name, rank and personality traits of some Senior Military Officers in the two army brigades nearby, his ammunition depot and others who visited the military station.
•    Photos of arms, ammunition, tanks other military vehicles (with their tactical numbers) at MFFR whenever he could visit it after April 2019.

Vikas also confessed to having received at least Rs 75,000 in total from his Pakistani handler for the information he has shared during this entire period. He used to receive them mostly on bank accounts of his and his brother, Hemant Kumar. The latter was found to have no links to the espionage case otherwise. Out of this sum, he had paid approximately Rs 9,000 in total to Chiman Lal for his assistance in lots of Rs 1000- Rs 2000 since their first meet.
