Explanation:

Only statements 1&3 are correct.

Auroras

• A significant geomagnetic storm is anticipated, triggered by a strong solar storm. This occurrence has the potential to "supercharge" auroras, creating a spectacular visual display in the night sky.

• Auroras are luminous phenomena that occur near the North (Aurora Borealis) and South Poles (Aurora Australis).

• They are caused by the interaction of charged particles from the Sun with the Earth's magnetic field and atmosphere.

• Auroras consist of gases and particles, including oxygen and nitrogen.

• The collisions of these particles with the atmosphere release energy in the form of light.

• The colors observed in auroras depend on the type of gas and altitude of the collisions.

Geomagnetic Storms and Auroras:

• Geomagnetic storms, triggered by solar events like coronal mass ejections (CMEs) and solar flares, enhance auroral activity. 

• CMEs are eruptions of plasma and magnetic fields from the Sun, while solar flares are bursts of energy.

• CMEs often occur alongside solar flares, which are explosions on the Sun's surface, but they are also known to occur independently.

Hence option 3rd is correct.
