At any time of year spectacular solar and lunar halos may appear in the sky, but this time of year is particularly good. No special equipment is needed to observe these beautiful sights, but care must be taken as solar halos appear around the sun. Remember to always use proper precautions when observing near the sun.
This image was taken a couple of days ago in front of my house. I have exaggerated the contrast of the image to better show the detail in the sky, however these phenomena are easily seen with the unaided eye. Keep an eye out for halos, sun and moon dogs, arcs and other atmospheric phenomena during the upcoming season.
