This is what the morning sky looked like today.
What is this phenomenon?
Starlink satellites are part of a project by SpaceX. In the sky, they can be observed as a row of bright lights moving at regular intervals, which is sometimes described as a “space train”. In Poland, these observations are possible and can be a fascinating experience for astronomy enthusiasts and others.
This phenomenon is best visible shortly after sunset or before sunrise, when the sky is dark.
