The sky at night

It doesn't get dark at this time of year. Not really dark.

Last night I had to go out to the car to get something and I noticed a faint glow still in the northwestern sky. It was around 11:30. A few hours later, I had to drive into Dublin and back. I was on the road for an hour - not normal for me to be out between 2 & 3 in the mornings - and what was a faint glow in the northeastern sky at 2am had developed into a fairly early morning sky by 3.
