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.

Mangaluru, May 29: The southwest monsoon is expected to reach the Karnataka coast on June 1 or 2, earlier than forecast by the India Meteorological Department (IMD).

Normally, Karnataka witnesses the onset of monsoon either five or six days after it had entered Kerala. However, this time, Karnataka will also witness the arrival of monsoon either on June 1 or June 2, according to meteorologists at the Karnataka State Natural Disaster Monitoring Cell (KSNDMC).

The gradual formation of two low-pressure areas over the Arabian Sea located close to the western peninsular coast and gaining momentum has helped Karnataka mark the start of the four-month-long rainy season expected to revive the back-to-back drought-stricken state.

Confirming the changes in the atmospheric pattern, Dr GS Srinivasa Reddy, Director KSNDMC said, “Karnataka will also witness the onset of monsoon on the same time that of Kerala.”

The early onset of monsoon over Karnataka coast is attributed to prevailing to weather pattern over the Arabian Sea. 

“The two low-pressure areas over the Arabian Sea are steadily gaining momentum. They may reach the peak by the weekend and may concentrate further into depression causing widespread rainfall in the peninsular region and thereby advancing the onset of monsoon over the region,” Dr Reddy explained.

The KSNDMC, based on the Indian Meteorological Department (IMD) forecast, stated that due to 'prevailing favourable conditions over the Indian Ocean and Pacific Ocean regions', the monsoon will be normal and above normal over coastal and south-interior Karnataka according to the present scenario.

The IMD, which had initially issued a forecast of five-day delay in the onset, had issued a fresh forecast on Wednesday cautioning the states along the West coast about the formation of two intense low-pressure areas in South-East and East-Central Arabian Sea region.

Following the forecast, a yellow alert has also been issued in Kerala and coastal areas suggesting significant rainfall starting from this weekend. “Fishermen have also been advised not to venture into deep-sea due to high turbulent conditions,” an IMD official revealed.
