Mumbai: It’s said that your shadow is your most faithful companion. It never leaves your side. But that’s not always true. Mumbaikars will not be able see their shadow for a few minutes on May 20 and May 21. This phenomenon is called No Shadow Day. The phenomenon takes place twice a year when the sun is directly overhead.
“It will be difficult to state the exact timings of the phenomenon. Zero shadow is likely to take place between 1pm and 2pm on May 20 or May 21,” Mahesh Palawat, Chief Meteorologist at Skymet Weather, said.
To observe this phenomenon, you can stand or place a vertical object under the sun close to noon and you will see the shadow getting shorter and shorter until it disappears for a few minutes. A Zero Shadow Day can only be witnessed by those living between the Tropic of Cancer and the Tropic of Capricorn.
Aurangabad and Jalna will experience this phenomenon on May 20, Nashik on May 21 and Nagpur on May 27.
“If we observe the sunrise (& sunset), we see its position shifting over the horizon day by day northwards from December 21, and then southwards from June 21. In India we call this Uttarayan and Dakshinayan,” an expert said.
“Between these two limits, the sunrays fall vertical on different latitudes on different dates. And on these dates, those living on that particular latitude will see their shadow disappear when the sun is right over head. Mathematically, it should be one particular day — but one can ‘see’ the zero shadow a day before or after,” he said.
Meanwhile, the Indian Meteorological Department (IMD) has said Mumbaikars will experience dry and sultry weather for the next few days. According to the weathermen, the sultry weather is because of high moisture content in the winds blowing into the city. “The winds blowing from the sea have a lot of moisture because of which the weather will turn sultry,” said K S Hosalikar, Deputy Director- General of Meteorology, IMD.
The temperatures will remain between 33°C and 34°C during this period.
