APOD: Lenticular Clouds over Mount Etna (2019 Aug 19)

Post by APOD Robot » Mon Aug 19, 2019 4:12 am

Image Lenticular Clouds over Mount Etna

Explanation: What's happening above that volcano? Although Mount Etna is seen erupting, the clouds are not related to the eruption. They are lenticular clouds formed when moist air is forced upwards near a mountain or volcano. The surreal scene was captured by chance late last month when the astrophotographer went to Mount Etna, a UNESCO World Heritage Site in Sicily, Italy, to photograph the conjunction between the Moon and the star Aldebaran<a/>. The Moon appears in a bright <a href="ap130414.html">crescent phase, illuminating an edge of the lower lenticular cloud. Red hot lava flows on the right. Besides some breathtaking stills, a companion time-lapse video of the scene shows the lenticular clouds forming and wavering as stars trail far in the distance.

While visiting Mammoth Lakes, I photographed the same crescent moon before heading off to visit Yosemite.

A few days later the moon was setting over Mammoth mountain.

Then it slipped over the top leaving a sliver between the trams.

The EPOD today is also lenticular clouds. What an interesting coincidence. It's neat to see the same phenomenon looking so different.

Wow, Fred, your last picture looks like a flock of birds was settling on the sliver of the Moon!

Well, a flock of ski lift gondolas, anyway.
