Random bright light flashes in the night sky

[Miha R]

Does anyone know what are those random flashes we often see in the night sky ? Like a camera flash but 1000 times brighter and bigger and usually happens near the horizon

Satellite reflections. Look up Iridium flare.

Hello, could it be electric trains?

When I lived in London they Flashed as I wandered by night.

Satellites, most likely. A few years ago I would have suggested Iridium satellites, but the ones that produced these very bright flashes are currently being or already have been de-orbited.

Bright flashes that illuminate an area at the horizon are often arcs from the contacts between electric trains and their power rail/ cable.

I often see them when waiting for the tube when visiting London.

Lightning ?
