Mangalyan sends the first image of Mars; The view is nice up here

Mangaluru, Jul 2: A frontline covid-19 warrior who was working in the Wenlock Covid hospital in the city has been tested positive for the coronavirus. 

Sources said that he was a pathologist working in covid testing laboratory of the Wenlock Covid hospital.

A few days ago, a senior health official had tested positive for the covid-19.

Dakshina Kannada has so far recorded deaths of 18 covid-19 patients. A total of 14,137 samples have been tested, out of which 13,040 have turned out negative, and 833 positive, including 10 persons from other districts. 372 cases are currently active.

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.

The Indian government has advised expats in the UAE and the Gulf against travel till flight curbs to their home country are lifted. This follows the clamour from some quarters for special repatriation flights to India.

A senior Indian External Affairs Ministry (foreign ministry) official said Indian citizens are safe in the countries they reside in. Prime Minister Narendra Modi had spoken to leaders of Gulf countries who assured him of their welfare, the Indian foreign ministry said. Meanwhile, the Minister of State for External Affairs, V Muraleedharan,, according to a Malayalam news report, also ruled out special flights.

Responding to a question from Khaleej Times on blue-collar workers' angst following job losses, Vikas Swarup, Secretary West in the foreign ministry said, "Insofar as repatriation is concerned, as you are aware, government has advised against all travel, and Indians have been told to stay where they are, As and when the (21-day) lockdown is lifted, and normal civil aviation resumes, Indians wishing to come back will be able to do so."

According to the latest data from the Indian foreign affairs ministry, there are 1,400 cases of Covid-19 infections among Indian expats in the Gulf region.

Swarup said infected Indians are being treated and kept in isolation in the UAE and Gulf. "Our missions have established contact with all the community leaders and the situation is under control," he said.

Cargo flights operating as usual  

Cargo flights carrying fruits and vegetables from India to the Gulf have not been disrupted and would continue as usual, the diplomat said. "We are also helping with medicines based on the requests of Gulf countries," he said.

Eight million India expats live in the Gulf, including close to three million in the UAE. They account for more than 60 per cent of remittances to their home country.

India's long lockdown of 21 says ends next Tuesday. Indications are that it could be extended. Some states like Orissa have already stretched it till the end of the month and others are expected to follow suit.

The government believes that the disease is now concentrated in 75 districts, and the focus should be on these areas to manage and contain the virus.
