Good Red Friday morning RP. Today's Astronomy Picture of the Day (APOD) is titled "Veins of Heaven." Noctilucent clouds (NLCs) have been prevalent this summer, as seen in this image taken above the calm waters of Vallentuna Lake near Stockholm, Sweden. Also known as polar mesopheric clouds (PMCs) they are understood to form as water vapor driven into the cold upper atmosphere condenses on the fine dust particles supplied by disintegrating meteors or volcanic ash. The NASA Aeronomy of Ice in the Mesosphere (AIM) satellite has been in orbit since 2007 to study NLCs. Remember past weather headlines about the "polar vortex" over the US? AIM found that winter weather patterns over the US were correlated with a decrease in NLCs over Antarctica. Veins of Heaven indeed.

Thank you, my friend Maj William W. 'Bill' Price for posting the Astronomy Picture of the Day (APOD) for July 26, 2019 entitled "Veins of Heaven."

"Explanation: Transfusing sunlight through a still dark sky, this exceptional display of noctilucent clouds was captured earlier this month, reflected in the calm waters of Vallentuna Lake near Stockholm, Sweden. From the edge of space, about 80 kilometers above Earth's surface, the icy clouds themselves still reflect sunlight even though the Sun is below the horizon as seen from the ground. Usually spotted at high latitudes in summer months the night shining clouds have made a strong showing so far during the short northern summer nights. Also known as polar mesopheric clouds they are understood to form as water vapor driven into the cold upper atmosphere condenses on the fine dust particles supplied by disintegrating meteors or volcanic ash. NASA's AIM mission provides daily projections of noctilucent clouds as seen from space."

Noctilucent Clouds above the city of Lahti in Southern Finland on July 25 2019.
Magnificent photo Maj William W. 'Bill' Price!!! A little research yielded a great 1 min-45 sec video of these beautiful Noctilucent Clouds in a time lapse capture! I believe your followers will enjoy it! https://youtu.be/5mLMr8POI_s
