Summary Authors: Marco Meniero; Giovanni Tumino

Shown above is a nighttime view of lava streaming down a flank
of Mt Etna as viewed from Naxos Bay, Sicily, on June 9, 2022. Note the
patch of light just above the glowing lava. This looks like it might be
a light pillar resulting from the glowing lava flow, however,
according to Marco Meniero, an expert on meteorological phenomena,
it's actually paraselene or moondog. The Moon can be seen at
the right side of the image. Note also the numerous glitter paths
(both photo). Click here to see a video in timelapse.

Photo details: Canon RA camera; SIGMA DG 50 mm lens; f/1,4;
f/4,5; 4-second single-exposure; ISO 1600.

Lace Lichen

Summary Author: Cindy Todd

Lace Lichen (Ramalina menziesii) is the official lichen of the
State of California. This lichen has a fishnet or lace look to it,
hence its common name. Prevalent along the Coast of California, it’s
both a source of food and nesting material for a number of different
animal species.

As a backpacker/hiker who lives in California, I see it often -- it
gives an eerie look to trees on a foggy morning. With the lace
structure hanging down off a branch, you sometimes feel like you're in
a horror movie where an evil witch suddenly appears. But I love
hiking in terrain where lace lichen thrives. Photo taken on July 16,
2022.

Dew Drops

Summary Author: Marco Meniero

When my mother asked me to photograph the roses in her garden with my
iPhone11 Pro, I happened to notice these beautiful dew drops. The
temperature at which the air is saturated with vapor is called the
dewpoint. When the surface temperature falls to the dewpoint, the
water vapor contained in the atmosphere condenses to form drops
(dew drops) on leaves and other surfaces. This process distinguishes
dew from precipitation that forms directly in the air – raindrops.
