Last night there was a huge display of NLCs to marvel at. Extension was about 120° from west to north-east.

At first the main part was visible in western direction while the north-eastern part was still mixed with the dark clouds at the lower edge.

Later, with increasing darkness, the north-eastern area became more and more intense while the western area lost its brilliance.
