Is this light in the sky a reflection (as on water vapor/smog) of what is happening at ground level?

It was likely the electrical discharge through the nitrogen in the air (guessing arc discharge in this case); it ionizes the nitrogen, which emits blue light when it's subsequently de-ionized.

I live about two blocks away. The lights dimmed and one of our breakers flipped. Then it got bad. My phone suddenly lit up, brighter than the night's electric blue sky, as everyone I've ever known called and texted to ask about what was going on.

Nothing interesting. Astoria is a pretty great neighborhood tho. We have a 24-hour fruit market next to another 24-hour fruit market.

That's interesting. What would make the breaker trip? Was it a regular overcurrent breaker, or some other kind?

This happens in Nigeria a lot (><) I hear and see a transformer explode multiple times per week.

What is the cause?

Could be any number of causes:

- overload + faulty breakers (or no breakers...)

- old age insulation failure

- coolant depletion

- overvoltage due to lightning strikes elsewhere

Resettable breakers (partially) work on magnetic fields, so in theory a power surge at a transformer (massive coils) could generate a strong enough field. Just a guess

What's the difference between the fruit stores? Is one better than the other or are they not directly comparable?

Earlier quoted context omitted.

Magnetic fields fall by distance to the 4th power (more or less) and are effectively zero at distances greater than double the size of the magnet (the pole separation).

I.e. unless that transformer was stupendously large there's no way the magnetic field would reach a home 2 blocks away.

But I appreciate you at least trying to answer, so thanks.
