On 21 June 2019 I witnessed an extremely rare sight in the skies over Belgium, called ‘noctilucent clouds’ (NLCs).
Noctilucent clouds are very high clouds (usually between 75-85km) that only occur on rare occasions. Scientists are still investigating these clouds and there is still no true consensus on how they are formed.
NLCs can only be observed during summer months, more specifically the period between end of May and beginning of July (for the Northern Hemisphere). After sunset and before sunrise, NLCs still reflect sunlight (due to their high altitude) and become visible. Usually this is late in the evening (between 11-12pm) ans also well before sunrise (between 4-5am).
According to preliminary meteorological reports, the NLC display of Friday 21 June 2019 was one of the biggest outbreaks ever recorded and was visible in many parts all over Europe.
