Noctilucent cloud activity is intensifying.
During the past couple of the weeks these silvery blue waves have been observed in the skies over the UK, mainland Europe, the Baltic and Russia. Northern latitudes between roughly 50° and 55° have been shown to be favourable with particularly bright displays.
To try and see them you need to be looking west, about half to one hour after sunset – when the Sun has dipped a few degrees below the horizon. If you see luminous blue-white tendrils spreading across the sky, you’ve probably spotted a noctilucent cloud. In the northern hemisphere, the best time to look is between mid-May and the end of August.
