LOOK UP TO THE NORTHERN SKY TONIGHT.
Look to the north tonight and you will have the chance to see the beautiful noctilucent clouds which appear electric blue in colour and are the highest clouds on earth.
They are located in the mesosphere at altitudes of around 76 to 85 km. noctilucent clouds are composed of tiny crystals of water ice.
Clouds in the Earth's lower atmosphere form when water collects on particles, but mesospheric clouds may form directly from water vapour in addition to forming on dust particles.
NLCs are only able to be seen in the northern hemisphere over the summer months and the best time to observe them is from between 11:30 pm and before dawn. After midnight the become more noticeable and can be seen by the naked eye just like normal clouds.

Noctilucent clouds are tenuous cloud-like phenomena in the upper atmosphere. They are made of ice crystals and are only visible in a deep twilight. Noctilucent roughly means night shining in Latin. They are most commonly observed in the summer months at latitudes between 50° and 70° north and south of the equator. These clouds can be observed only during local summer months and when the Sun is below the horizon for the observer, but while the clouds are still in sunlight. They are the highest clouds in Earth's atmosphere, located in the mesosphere at altitudes of around 76 to 85 kilometres (47 to 53 mi). Noctilucent clouds are not fully understood and are a recently discovered meteorological phenomenon; there is no confirmed record of their observation before 1885, although they may have been observed a few decades earlier by Thomas Romney Robinson in Armagh. Noctilucent clouds can form only under very restricted conditions during local summer; The occurrence of noctilucent clouds appears to be increasing in frequency, brightness and extent.

Munich firefighters received some 320 emergency calls due to the storm, Germany's Focus magazine reported.
Monday storms also lashed various other parts of Germany, including the northwestern city of Mönchengladbach, where heavy rain flooded basements and caused streets to run with water. Hail and rain also reached the eastern German state of Saxony.
Weather experts warned strong storms could continue on Tuesday, with the country's capital Berlin likely to be affected. According to local radio Rbb24, meteorologists from the national weather service Deutsche Wetterdienst and private MeteoGroup foresee hail between 3 and 5 centimeters in diameter and gusts of wind up to 120 km/h (75 mph) in Berlin and nearby Brandenburg.
