Full Moon 

"The glory"- softly colored rings around the shadow of an airplane. 
Atmospheric optics expert Les Cowley explains what causes it: "These rings are formed when light is scattered backwards by individual water droplets in the clouds. The more uniform the size of the droplets, the more rings you will see. They swell and contract as you travel over clouds with smaller or larger droplets."

Astreoid- 1 LD


Coronal Holes: 



Space Weather Storms 

Coronal Mass Ejections (CMEs): Massive bursts of highly charged particles (neutrons, protons, and heavy nuclei) from the sun's corona. The corona is the outermost layer of the sun. 




Geomagnetic Storms: A temporary disturbance of the Earth's magnetic field (magnetosphere). It is caused by solar winds that strike the Earth's magnetosphere




Coronal Holes: Coronal holes are part of the Sun's corona and are constantly changing and reshaping because the corona is not uniform. Coronal holes are areas where the Sun's corona is darker, and colder, and has lower-density plasma than average because there is lower energy and gas levels. -https://en.wikipedia.org/wiki/Coronal_hole
