Wasn't the best biggest halo i've seen
The coronae is much smaller than the 22° halo which can also ring the sun and moon. The corona also has nothing to do with the Sun's outer atmosphere visible during a total eclipse and confusingly given the same name.
Coronae are produced by the diffraction of light by tiny cloud droplets or sometimes small ice crystals.
Halo caused by refraction
Corona caused by diffraction
