While going out to my car this afternoon to get some lunch I noticed a great looking, complete solar halo right at noon time. For a bonus, I also noticed a Circumhorizon arc just below it.
At first not knowing the proper name of the arc below the sun I did some quick research online and found this great website called Atmospheric Optics. It is a great reference sight for many atmospheric irregularities.
Yet again I am amazed by mother nature producing beautiful sights in the sky!
