The date on which it rises the farthest to the north is roughly June 21, the summer solstice and the longest day of the year in the Northern Hemisphere. In the winter, the sun rises somewhat south of due east.

So, in the Northern Hemisphere you have:

• Vernal equinox(about March 21): day and night of equal length, marking the start of spring.
• Summer solstice (June 20 or 21): longest day of the year, marking the start of summer.
• Autumnal equinox(about September 23): day and night of equal length, marking the start of autumn.

Just remember that solstices are the longest and shortest days of the year, while equinoxes occur when the day and night are equally as long.

The Equinox (Vernal & Autumnal) These events are referred to as Equinoxes. The word equinox is derived from two Latin words – aequus (equal) and nox (night). At the equator, the sun is directly overhead at noon on these two equinoxes.

Kolkata has the longest day in the month of June. Over the course of June in Kolkata, the length of the day is essentially constant. The shortest day of the month is June 1, with 13 hours, 25 minutes of daylight and the longest day is June 21, with 13 hours, 31 minutes of daylight.

Having the sun directly overhead can happen only between the Cancer and Capricorn tropics. That is, only the places between 23.5° of latitude north and 23.5° of latitude south. On the Cancer tropic (23.5° latitude north) it will happen once every year, on the day of the northern hemisphere solstice (about June 21st).

The Sun is currently in the constellation of Gemini.

This angle is called the solar declination. It is defined as the angular distance from the zenith of the observer at the equator and the sun at solar noon. It is positive when it is north and negative when it is south.

The declination angle, denoted by δ, varies seasonally due to the tilt of the Earth on its axis of rotation and the rotation of the Earth around the sun. The declination of the sun is the angle between the equator and a line drawn from the centre of the Earth to the centre of the sun. …

Declination can mean a bending or sloping downward. A declination can also be a polite refusal, especially in a formal or official situation. In this sense, it is a noun form of the verb decline, meaning to refuse or to turn something down.

1 : the angle made by a descending line or plane with a horizontal plane. 2 : the angle between the direction indicated by a magnetic needle and the true meridian. — called also magnetic declination.

Angle of declination at a place is the angle between the direction of the earth’s magnetic field and the horizontal in the magnetic meridian at that place. Neutral Points. At certain points the field due to a bar magnet may be completely neutralized by the horizontal component of the earth’s magnetic field.

The following equation can be used to calculate the declination angle: δ=−23.45°×cos(360/365×(d+10)) where the d is the number of days since the start of the year The declination angle equals zero at the equinoxes (March 22 and September 22), positive during the summer in northern hemisphere and negative during winter …

When working with a map and compass there are usually three different norths to be considered: True North, Grid North and Magnetic North. There is now a fourth: Google Maps North.

Answer. The range of dip is from -90 degrees (at the South Magnetic Pole) to +90 degrees (at the North Magnetic Pole). Contour lines along which the dip measured at the Earth’s surface is equal are referred to as isoclinic lines. The locus of the points having zero dip is called the magnetic equator or aclinic line.

The angle of dip is 0° when the dip needle rests horizontally while the angle of dip is 90° when the dip needle rests vertically.

90 degrees

The angle of dip is maximum e. 90° at the magnetic poles. The angle of dip is minimum i.e. 0° at the magnetic equator.

The Earth’s Magnetic Field The range of dip is from -90 degrees (at the South Magnetic Pole) to +90 degrees (at the North Magnetic Pole). Contour lines along which the dip measured at the Earth’s surface is equal are referred to as isoclinic lines.

90°

Angle of dip is maximum at the poles. A compass needle points to the north because it is the N pole of the compass and is attracted by the S pole of the earth. This does not mean that there is actually a magnet as such inside the earth. Rather, an electric current in the earth generates a magnetic field.

90∘

The angle of dip is. Horizontal component of earth’s magnetic field becomes zero. ⁡ θ = B cos ⁡ A freely suspended magnet will become vertical at magnetic poles.
