Which of the following statements regarding 'aurora' is/are correct ? 1. The solar wind upon reaching the Earth's atmosphere is directed towards two magnetic poles and a colourful display of lights is seen in the night sky. 2. The particles interact with the different gases of the atmosphere and each gas glows with a particular colour. 3. In April 2023, aurora was captured in the night sky in India by the Indian Astronomical Observatory at Hanle, Ladakh. Select the answer using the code given below :

Auroras are formed when the solar wind (charged particles from the Sun) reaches Earth and is channelled by the planet's magnetic field towards the polar regions, producing colourful light displays — so statement 1 is correct. The particles excite different atmospheric gases (oxygen produces green and red light; nitrogen produces blue and purple), confirming statement 2. In April 2023, the Indian Astronomical Observatory at Hanle, Ladakh, did capture rare aurora activity in the Indian night sky due to a strong solar storm, making statement 3 correct as well. Hence all three statements are correct.
