I'm sorry but I really don't know what I'm supposed to be looking at in this video. Does it have something to do with that flashing arrow? Please
explain.
Halos form when the sunlight or moonlight is refracted or bent by ice crystals associated with thin-high level clouds, like cirrus or cirrostratus.
Often, a halo around the moon or sun is an indicator of cloudy or rainy weather as high level cirrus and cirrostratus clouds that cause halos tend to drift ahead of frontal systems (especially warm fronts) that produce rainfall.
