John Rowlands, MW1CFN will be active with special call GB0NLC from Rhosybol, Wales, celebrating the 2018 noctilucent cloud (NLC) season, 3 - 8 July 2018.
NLC are sometimes called 'space clouds', on account of their very great altitude of some 50 miles/82km. This is about seven times higher than any weather clouds.
Unlike weather clouds, NLC remain lit by the below-horizon sun at night from moderate-high latitudes
There are no known records of NLC before 1885, and a link with climate change is proposed.
NLC are sometimes associated with VHF radar echoes from the mesosphere, and with sporadic E events.
You can see NLC during late May to early August in the northern hemisphere, from latitudes spanning roughly 50-60 degrees north. Exceptionally, they may be seen from slightly lower latitudes.
QSL via LOTW.
DXCC Country - Wales, GW.
