The NLC season of 2015 has started! I observed my first NLC’s for this year in the night between 1st and 2nd of June 2015. The NLC’s covered pretty much the whole sky! They extended from northern sky all the way to the southern wky, where only the shadow of the Earth was limiting the visibility of the NLC’s. The most dominant NLC forms in this display were belts and large scale whirls. Aslo some wave-stacks were visible.
