It's possible, but since the Aurora is a high northern or southern latitudes phenomena ( Auroral activity is in high latitudes because of the magnetic fields near the poles) and since daylight is so extensive in the summer months the sky is often to bright for any worthwhile viewing.
It's also not a good time right now. Activity on the sun follows an 11 year cycle the last maximum was in 2000 so the sun is at it's quietest at the moment.
No. From Britain there is no true darkness in the northern sky in June since the Sun is less than 15 degrees below the northern horizon, even at midnight.. Remember, at 66 degrees North the Sun doesn't set on 21st June (summer solstice) The Aurora Borealis is seen in the northern sky and is faint in absolute terms. It can only be seen in a dark sky.
