I live on bag søndermarken 23, 4th floor with windows looking north and west Copenhagen, Denmark

I spend a lot of time just staring at stars, looking at flight radar etc.

On this clear night i observed a bright light looking 3x brighter and 3x size of what jupiter looked like yestarday, which was huge and bright.

It was 100% stationary, and it then faded into nothing in 1-2 seconds.

What was it?

I usually look north and enjoy watching the planes and usually check flight radar, nothing matching what i was seeing.
