- Sun will enter northern hemisphere after March 21, summer season will start
On Sunday, March 21, the Sun will be at the equator. Due to which day and night will remain equal. That is, both will be of 12–12 hours. It is also called Vasant Sampat. Last year, this geographical event took place on 20 March. Therefore, the experts of geographical calculation have stated the days of hemispherical changes of the Sun on 20–21 March and 22–23 September. After these, there are changes in the time of day and night.
When the Sun is at the equator, the Tropic of Cancer and the Tropic of Capricorn. Then the four equinoxes are formed in March equinox, June solstice, September equinox, December solstice respectively. This time, on March 21, Sunday, on the spring equinox, the sun will be at the equator. At this time, if a person is standing on the equator, then the sun will be visible directly above his head.
Sun’s entry into the Northern Hemisphere
On March 21, the Sun will now enter the Northern Hemisphere after the Sun arrives at the equator in Aries. Due to the arrival of the Sun in the Northern Hemisphere, countries including India which are present in the Northern Hemisphere, the time of day will gradually increase and the nights will become shorter. This situation will remain till 21 June. This position of the sun staying perpendicular to the equator is also called Vasant Sampat.
The position of the sun at 0 degrees as seen in the observatory
According to Dr. Rajendra Prakash Gupta, Superintendent of Jeevaji Observatory Ujjain, the position of the sun will be seen at 0 degrees with the cone device and the umbilical cord. He told that on 21 March, the shadow of the cone will be seen moving in a straight line throughout the day. Earlier, from 22 September to 20 March, there was sunshine on the southern part of the pulse ring device. Now from March 21 to the next 6 months i.e. September 22, the northern round part of this device will be sunny. In this way, changes in the hemisphere of the Sun can be directly observed.
Where does the equator pass
The equator passes through fourteen countries. Most of the equatorial regions on the Earth’s surface are oceanic. Places around the equator are good for establishing a space center. The Guyana Space Center, Kourou and French Guyana’s Space Center are also present on the equator.
