Pink Flash of Light

Hello, I was driving home late last night. Everything was normal until I saw a giant flash of pink light in the sky. It only lasted for less than a second. My first thought was that it was some kind of explosion so I immediately turned off the radio but did not hear anything. When I got home I asked my mother if she heard anything since the windows were open, she said she didn't hear anything.
I cannot make sense of what it was, the sky was clear so it couldn't of been lightening. Since I did not hear anything and my mother a few minutes away from me did not hear anything, I don't think this was an explosion of some sort.
There could very well be a natural explanation for this, it could have been a meteor burning up in the atmosphere or a piece of debris. I just find it odd that there was not a noise.
Since I was driving and it occurred very fast, I do not have a photo or video of the flash of light.
