Scenes of wonder and amazement here in Walnut Creek today as we witnessed a halo appearing around the sun!
What could it mean? It's not every day that a degree in theology is useful, but on this occasion I was able to advise the restive locals that either:
a) the sun god is demanding a sacrifice,
b) the end times are approaching, or
c) light is passing through the 60° apex angle of hexagonal ice prisms in the atmosphere and being deflected twice resulting in deviation angles ranging from 22° to 50°, where the angle of minimum deviation is almost 22° (or more specifically 21.84° on average; 21.54° for red light and 22.37° for blue light) and this wavelength-dependent variation in refraction causes the inner edge of the circle to be reddish while the outer edge is bluish - as no light is refracted at angles smaller than 22° the sky is darker inside the halo.
What could it mean?
Attempting to read the signs with a teaspoon (or, at least, block out some glare to get a better pic).
And here's a photo of a baby looking cute in a bouncer.
