EFHK, Helsinki Vantaa runway 15.

OH-LWL Airbus A350-900 is coming home from somewhere probably hotter.

You can see this tower here on gmap

It seems to be a primary radar for ground traffic.

From that angle, OP worked an early shift on the airport, nice shot sir !

(You can see the rwy 15 and YB taxiway junction on the photo and on this chart)
