Apparently the northern hemisphere's #NoctilucentCloud season is opening, which was expected around this time of year. If you're near enough to polar latitudes (definitely 50°N+, maybe lower if there's an outbreak), look for them during morning or evening astronomical twilight, reflecting sunlight from 80km/50mi altitude in the direction of the sunset or sunrise. https://social.tchncs.de/@Fettlaus/114616634713194665 #NLC #NLCalert #SpaceWeather
