Most of us have seen halos around the sunlight . We know why they happen . And then there are Bottlinger ’s Rings . No one has figured out why they be .
It ’s not strange , when locomote by plane , to look down and see the sun reflecting off a swarm below you . This little patch of reflected luminance is called a “ subsun . ” Sometimes you ’ll see a circular halo around the subsun . And sometimes , without knowing it , you ’ll see an atmospherical mystery .
rotary halos are clean common — they ’re have by ice rink crystals of a specific shape and preference . But there is an rum phenomenon that sometimes have these rings to debase and go elliptical . These ellipse rings , called Bottlinger ’s Rings , appear mostly to airline business travelers for only a few seconds at a time , and scientists still are n’t certain why they appear at all .
you could see more pictures of the ringshere . The departure from a circular halo is pernicious , but unaccountable . As best as anyone can calculate , Bottlinger ’s annulus come from hexagonal lechatelierite with sides that slope at an slant of one to three level . The crystals have to be hanging almost flat in the air . One team of scientists estimated that the temperature has to be around -15 ° hundred to make the conditions just right .
That being said , even after playing around with the incline and orientation course of the crystals , many scientist ca n’t get their model to twin up absolutely with the few motion-picture show of Bottlinger ’s Rings that citizenry have do to get . So perhaps we have to come up with a whole different theory for the optics of these rings . Any idea ?
