Noctilucent clouds (NLCs) over the South Pole remain missing as of December 29, 2020– an unusual occurrence as the clouds are expected to appear in the middle of the month. The southern stratosphere seems to think it's winter. In early December, Dr. Tony…
Noctilucent clouds (NLCs) over the South Pole are missing this year, but consider it only the tip of the iceberg, Dr. Tony Phillips of the SpaceWeather said. Missing NLCs is just one of the curious weather patterns currently underway at the southern end of our…
Rare dark red noctilucent clouds appeared over Vallentuna, Sweden on July 25, 2020, and were recorded by P-M Heden. This type of NLCs is rare and not fully understood, Dr. Tony Phillips of the SpaceWeather.com reports. Research in the 1970s revealed that much of the…
Observers across Europe, from Scandinavia to the Adriatic coast, are reporting major noctilucent clouds (NLC) outbreak on July 5 and 6, 2020. The outbreak comes on the heels of July 4th sighting over southern California, U.S. — where in 2019 a record was set for…
Temperatures at the mesosphere have been breaking 14-year records over the past few days, according to Lynn Harvey of the University of Colorado Laboratory for Atmospheric and Space Physics. This causes noctilucent clouds to spill across the Arctic and descend to…
The Northern Hemisphere noctilucent cloud (NLC) season has officially begun. The first cloud was detected by NASA's AIM spacecraft inside the Arctic Circle on May 17. The detection marks one of the earliest starts in the 14-year history of the spacecraft. …
Public interest for noctilucent clouds rose sharply in 2019 after record-setting outbreak across the northern hemisphere. The 2020 season is expected to start mid- to late-May or early June, but at the moment, it doesn't seem like 2020 will be a repeat of 2019….
A spectacular outbreak of rare polar stratospheric clouds (PDCs) was reported around the Arctic Circle, starting December 30, 2019. The display lasted nearly an hour and was commonly regarded as the brightest display that any of the locals have ever seen. The…
An atmospheric wave about half as wide as the Earth is supercharging noctilucent clouds (NLCs) in the southern hemisphere, with NASA's Aeronomy of Ice in the Mesosphere (AIM) spacecraft detecting the phenomenon in this series of south polar images from November…
The 2019 northern hemisphere noctilucent clouds season is turning out to be the most remarkable ever. After record strong start of the season at the end of May, NLCs were seen for the first time as low as San Francisco Bay Area, California on June 9 and throughout…
