The nights around the Vernal Equinox are prime for aurora spotting. Why Spring? No one really knows, but groups of aurora watchers are geared up and ready for the spectacular colours in the northern skies. I am one of these people, and I am set.
Spring is the time that favours the magnetic link between the Sun and Earth. During the Vernal Equnox Earth’s magnetic field is positioned for the best magnetic connection with the Sun. During this time the energy from the Sun causes bursts of activity in the rarefied gases in our atmosphere. Voila! Aurora. It is more complex than that, but that is the jist of it. Let me know if you want more information on aurorae. They are one of my fields of research.
You can also go to NASA aurora info.

i dont understand how the solar activity in sun is related to magnetic reconnection…?
