The appearance of aurora in the evening skies rise and fall in frequency with sunspot numbers, and there are maxima in March and September when the Earth in its orbit is in a better location with respect to the Sun to get 'blasted' by solar storms in the mid-latitude zones of the Sun.
Auroras occur when charged particles from the sun enter Earth's atmosphere and interact with gases in the upper atmosphere, typically near the magnetic poles. This phenomenon is more common during periods of high solar activity, such as during the solar maximum of the 11-year solar cycle.
Auroras can occur during the day or night, but they are typically easier to see at night when it is dark. However, strong solar activity can sometimes create auroras that are visible during the daytime as well.
Auroras occur in the thermosphere, which is the region of the atmosphere located between the mesosphere and the exosphere. This is where charged particles from the sun interact with gases in the Earth's atmosphere, creating the colorful light displays known as auroras.
Auroras occur in the thermosphere, which is the second-highest layer of Earth's atmosphere. The thermosphere is located between the mesosphere and the exosphere, at an altitude ranging from about 80 km to 600 km above the Earth's surface.
The rarest color in auroras is blue. Blue auroras occur at higher altitudes than other colors, around 60 miles above the Earth's surface. They are less commonly seen compared to green and red auroras.
Auroras form in the thermosphere, which is lower than the exosphere. The interaction of solar wind with Earth's magnetic field creates charged particles that collide with gases in the thermosphere, producing the beautiful light shows known as auroras.

September to October and April to May
Auroras are not directly related to sunspots. However, sunspots are associated with solar flares and coronal mass ejections, which can cause geomagnetic storms on Earth. These storms can enhance aurora activity, making them more likely to be visible at lower latitudes.

Ionosphere of Near northern hemisphere polar regions
The auroras that are experienced near the polar regions occur because of the strength of the earth's magnetic field. The magnetic field is not very strong at the equator.
Auroras have no definite size. They occur when charged particles from the Sun ionize particles in the upper atmosphere as they spiral in toward Earth's magnetic field. Auroras may be localized in one area, or may extend from horizon to horizon in the sky.
A planet needs a magnetic field, an atmosphere, and solar wind to have auroras. Auroras occur when charged particles from the solar wind interact with a planet's magnetic field and atmosphere, creating beautiful displays of light in the sky.
