All can be explained by magnetic reconnection and gravity gradients.
Fireball and aurora seasons occur around the equinoxes. Magnetic reconnection between the Sun and Earth is strongest at this time.
The center of the Sun is aligned with the Earth's equator at this time, likely perturbing any debris or space junk in orbit around the Earth.
Simple really and no conspiracy. Occam's Razor is your friend.

"Fireball season, occur around equinoxes"
NASA says:
"Autumn is the season for sporadic meteors," says Cooke. "So why are the sporadic fireballs peaking in spring? That is the mystery."
"Researchers who study Earth's meteoroid environment have never come up with a satisfactory explanation for the extra fireballs. In fact, the more they think about it, the stranger it gets.

Not quite on par...
Regardless if all this was "normal" charts would be looking like this:
Notice the recent huge spikes?
Compare that to "fireball season" searches for more proof:

There is an obvious tremendous recent uptick of fireballs, if the answer is "well it's normal and always has happened", the data isn't supportingAs far as the magnetic goes, only recently has these recurring disturbances been occurring, like also as recently so call "fireball season" now exists and fireballs are on the increase.
Go through all the data, it's clearly evident there's a recent change over the past couple years.
