Full moon and the ‘Belt of Venus’ glow over Lisbon throughout 1st eclipse of 2020 (photograph) – House.com

Miguel Claro is knowledgeable photographer, writer and science communicator primarily based in Lisbon, Portugal, who creates spectacular photos of the evening sky. As a European Southern Observatory photo ambassador, a member of The World At Night (TWAN) and the official astrophotographer of the Dark Sky Alqueva Reserve, he makes a speciality of astronomical “skyscapes” that join Earth and evening sky. Be a part of Claro right here as he takes us by means of his {photograph} “Penumbral Lunar Eclipse and Anti-Twilight Arch as Seen From Lisbon Metropolis.”

A cityscape view captured from the highest point of Lisbon reveals the primary full moon of the 12 months, rising above the capital of Portugal on Jan. 10, with the Tagus River seen within the background. 

This photograph was taken throughout a penumbral lunar eclipse, which occurs when the moon passes by means of Earth’s faint outer shadow. Throughout nautical twilight, it’s troublesome to note this faint shadow on the moon’s disk. Nevertheless, a associated phenomenon is seen virtually day-after-day, generally known as the Earth’s shadow. In line with Atmospheric Optics, a skywatching web site run by physicist Les Cowley, this shadow is seen within the reverse half of the sky to the sundown or dawn, and it seems proper above the horizon as a darkish blue band. 

“Instantly above it, the place the night air remains to be lit, glows a pink band known as the anti-twilight arch, or ‘Belt of Venus,'” Cowley wrote. This phenomenon is brought on by backscattering of refracted daylight because of effective mud particles excessive within the ambiance.

After wanting fastidiously at this picture, my TWAN colleague David Malin, a photographic scientist and some of the distinguished night-sky photographers on the earth, observed a phenomenon that’s rather more troublesome to see. The blue-gray shade beneath the reddish Belt of Venus is because of a phenomenon generally known as the Chappuis absorption impact, which occurs when sure wavelengths of daylight are absorbed by ozone within the ambiance. Bob Fosbury, Malin’s good friend and a famend astronomer, described the physics of this delicate coloration in an easy-to-read article revealed within the European Southern Observatory’s astronomy journal, The Messenger. 

Whereas the primary lunar eclipse of the 12 months was rising above Lisbon, by coincidence, a flying seagull was caught within the scene. The picture additionally reveals a powerful atmospheric turbulence, inflicting a transparent distortion on the moon’s spherical disk. Two small notches are seen within the decrease half, in addition to two more-subtle refraction notches at an identical distance from the higher limb.

To seize this single shot, I used a Nikon D810A digicam with the ISO set to 1250 and a 150-600mm Sigma Sport lens set to 440mm at f/6.3. The publicity time was 1/400 seconds.
