CM declares three-day mourning

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.

Mangalore University has been participating in the campus bird count a sub-event of ‘Great backyard bird count’ (GBBC) organized by Bird Count India for the past 5 years. This year, CBC was held from 14th to 17th February of 2020 across various campuses in India.

This year the four days event was successfully ended up with the sightings of 103 species of birds from various locations across the campus spread on 300 acres. In this Black Drongo, Black Kite, Brahminy Kite, Common Iora, Green Wabler, Purple-rumed Sunbird, Red-whiskered Bulbul, White-cheeked Barbet, Jungle Babbler and Plum headed parakeets were the common birds, and also observed House Crow with nest and nestlings, Indian Robin nest with eggs, Bronzed Drongo constructing the nest and Shikra mating and carrying nesting materials.  Whereas Yellow-billed Babbler is rare in the campus, Ashy Drongo, Barn Swallow, Booted Eagle, Grey Wagtail, Indian Pitta etc. were migratory birds, Grey-headed Bulbul (Near Threatened bird), Rufous Babbler and Grey-headed Bulbul were Western Ghats Endemics  and Brown Wood Owl, Barn Owl, Spotted Owlet, Nightjars (Savanna, Indian and Jerdon’s) and Sri Lanka Frogmouth were nocturnal birds. Blue-eared Kingfisher Grey-bellied Cuckoo which was very rare and new additions to avian list of the campus.

In the first year (2016) of Mangalore University’s CBC recorded 77 species, in 2017 recorded 95 species, in 2018 recorded 110 species and in 2019 recorded 107 species of birds. However some of the common species like Rose ringed parakeets, Blue tailed bee-eater, Nilgiri Flowerpecker and Indian roller etc., sighted last year were not seen this year. But with 2 new additions from this CBC, the checklist of Mangalore University Campus has been updated with a total of 141 species.

This event was coordinated by Vivek Hasyagar from the Department of Applied Zoology and Maxim Rodrigues from the Department of Marine Geology. Survey trails were led by more than 60 students and research scholars from various Departments of Mangalore University includes Applied Zoology, Biosciences, Microbiology, Botany, Physics, Chemistry and Material Science.  In addition, some enthusiastic participants from St. Aloysius College had involved in identifying the birds around the campus.

Quote:

Wild/planned fire affects negatively on the existing ecologically sensitive areas in and around the campus especially in lateritic grasslands. Because many insectivorous birds are dependent on these lateritic grassland habitats for their food and breeding grounds for many ground dwelling birds like Yellow wattled lapwing, Red wattled lapwing, Indian Robin and Barred buttonquails. Conserving these habitats will be helpful in protecting these birds.

Quotes from the participants: “The Campus Bird Count 2020 at Mangalore University was an experience of its own kind. Observing birds in their natural habitat gave me new perspective of viewing them not only as another living being, but as equals, or even of higher intelligence. The Campus Bird Count is an important step towards documenting bird life year after year, and creating awareness amongst youngsters, so that proper conservation steps can be taken to protect them from human interference”.

Chamarajanagar, Jan 3: The residents of Galipura layout in Chamarajanagar city boycotted the annual Community Based Survey (CBS), conducted by the Health and Family Welfare department, mistaking it to be the National Register of Citizens (NRC).

Majority of the residents in the layout belong to Muslim community. The people, who mistook CBS to the NRC survey, got into arguments with the Asha workers, who were given the responsibility of collecting information. They even tore the forms into pieces and vent their ire.

The Health Department conducts CBS every year in the urban areas and collects all details including Aadhaar number, residential address, details of family members, health problems and others.

Fifteen Asha workers were deputed for the survey in the layout. A few youths started questioning them alleging it to be an NRC survey and started arguing with them.
Tahsildar Mahesh, District Health and Family Welfare Officer Dr N C Ravi, with the help of Muslim leaders cleared the confusion. The community leaders assured of explaining it to the residents and extend cooperation to the survey.
