Yellow composite - a Hawk's-beard I think

Observation - Yellow composite - a Hawk's-beard I think. Description: Found growing at a bus-stop on my way home. I am determined to be able to get further than just 'yellow composite', but it takes a bit of pulling things apart, and then they don't quite seem to fit the descriptions.

Found growing at a bus-stop on my way home. I am determined to be able to get further than just 'yellow composite', but it takes a bit of pulling things apart, and then they don't quite seem to fit the descriptions.
Achenes are about 4mm long excluding beak, about 8mm including beak. Flower-heads about 15mm before they shrivelled up, outer ligules pinkish-orange below, quite a light yellow above.
