Additionally, viewers should keep their eyes open for (https://earthsky.org/astronomy-essentials/what-is-earthshine) earthshine
as it will illuminate the darkened portion of the young moon tonight.
In this case, the flare is due to the very bright Earthshine
. Close passes by Venus and Mercury may occasionally create similar patterns in the future, but these are limited cases and do not affect the science operations of the instrument, NASA said.
During a sunlight Earth can illuminate the Moon's surface being lit phenomenon 'Earthshine
' Capturing images like these has become much easier since the opening of the new building, the Gillian Dickinson Astroimaging Academy.
For a couple of nights after the new moon, it's also possible to see Earthshine
on the surface of the moon.

Aircraft radiations are composed of aircraft plume radiation, aircraft hot parts radiation, skin radiation, reflected sunshine radiation, reflected earthshine
radiation, and reflected skyshine radiation .
You once again have an opportunity to see a very thin crescent Moon with Earthshine
in a dark sky.
The nighttime copolar Mie-channel performance of ATLID should be similar to the 532-nm CALIOP channel, but better daytime sensitivity is expected because of reduced background noise due to the smaller field of view, the narrower 0.3 nm filter, and the lower levels of earthshine
than at 532 nm.
Look for dim, gray earthshine
illuminating the crescent Moon's night parts--the beautiful "old Moon in the new Moon's arm's" effect.
The delicate glow of the "dark side" of the Moon is light reflected off the Earth, called "earthshine
Herschel also argued the case for active volcanism and topographic change on the lunar surface, observing in 1787 three glowing 'volcanoes' on the Moon's dark hemisphere--almost certainly the bright ray craters Aristarchus, Copernicus and Kepler, illuminated by earthshine
. Indeed, if we leave aside Robert Hooke's 'bubble' theory of crater formation a century or so earlier, Herschel might well be regarded as the first 'British' selenographer to argue for a volcanic theory of crater formation--a view that, as we shall see, came to dominate and shape nearly all later British thinking about the nature of the Moon.
Last week the sliver moon was like a giant silver scythe lying in the night sky brilliantly lit by the phenomenon of Earthshine
when light from the sun reflects from our spinning planet onto the visible moon's surface.
