Sun’s Rotation and Its Unique Phenomenon

• The sun rotates about its axis, but with differential rotation.
• The rotation period near the equator is 26.5 days, at the sun spot zone it is 27.3 days, and at the pole it is 31.1 days.
• The sun’s core temperature of 15 million degrees K and surface temperature of 6,000 degrees K create a high-pressure plasma state.
• The north and south poles are designated for calculations.
• Daily observations of spots, filaments, and plages help calculate the sidereal rotation period.
• The reason behind this phenomenon remains a mystery to solar physicists.
