On a Valentine’s Day like today, one might be prone to seeing heart-shaped symbols where they don’t actually exist.
Well this featured heart was really a lenticular cloud that appeared in July 2015 above Mount Cook National Park in New Zealand.
As explained by Astronomy Picture of the Day:
The cloud’s red color was caused by the Sun rising off the frame to the right. Lenticular clouds are somewhat rare but can form in air that passes over a mountain. Then, vertical eddies may form where rising air cools past the dew point causing water carried by the air to condense into droplets.
Here a companion video showing that the lenticular cloud was mostly stationary in the sky but shifted and vibrated with surrounding winds. The love cloud appears after 1:29:
Happy Valentine’s Day to everybody.
