This month – June 2014
Look out for Noctilucent Clouds (Neo-Clouds).

Increasingly common summertime of Neo-Clouds (NLC) will begin in this month (every June) – these clouds are not normal clouds; rather be at altitude of 50 miles in the coldest part of our atmosphere that appears bluish-silver or bluish-white and can be viewed over the North-East horizon, when the Sun is between 6 and 16 degrees below the horizon (see below for the diagram).
