The photo sequence shows the green flash phenomenon during
moonset on May 15, 2022, as observed from Porto Ottiolu, Sardinia,
Italy. Most of us have heard the color “blue” used to describe the Moon
but rarely is the color “green” mentioned. Green flashes and green
colored rims of the Moon occur because of atmospheric dispersion –
near the horizon our eyes detect separate images for red, yellow, and
green colors. Since green is the topmost color we see, when atmospheric
conditions are right a burst of green light may be briefly noted as the
upper rim dips below the horizon.

Summary Author: Anthony Ayiomamitis

We were very fortunate to have had a great stretch of weather here in
Greece during late October that allowed us to observe the second and
final solar eclipse for 2022. This was a partial eclipse, on
October25, but it shaded as much as 86% of the Sun for some
parts of western Siberia. It was visible to residents of Europe,
northeast Africa, the Middle East and western Asia. The eclipse depth
for Athens, Greece, was approximately 38%, with the eclipse having a
duration of two hours and fifteen minutes. Maximum eclipse occurred at
13:42:56 (UT+3 local time). Note, as an added bonus there were three
active solar regions; one at each of the limbs to the east and to
the west (AR3131 and AR3126, respectively) as well as another fainter
group just south of center (AR3130).

Summary Author: John Chumack

Shown above is 52 Cygni (bright star at upper center) and NGC-6960
(Veil Nebula – " The Witches Broom"), a supernova remnant found
in the constellation of Cygnus, A massive star exploded about 5,000
years ago leaving this beautiful filamentary remnant amongst a
star-studded field of the Cygnus region of the Milky Way. Though it
may look spooky at this time of year, the Veil Nebula is in essence a
cloud of ionized gas and dust located about 2,400 light years from
Earth. Image taken from my backyard in Dayton, Ohio on August 23, 2022.
