Have seen that many, many times while in Alberta, Canada but just during very cold winter nights. Usually more than -20C. Now I know what that was....Thanks.

If it happened 6 months ago (september) in Ohio, I don't think it would be cold enough for ice cristals. record low temperature in Toledo, ohio in september is only -3 celsius.
It did happen to me and it was Far East Ohio--- somewhere between the booming metropolises of New Waterford and Alliance. It was in 2013 and I could be off on precisely when I witnessed them occurring (two times last year).

Don't confuse air temperature at ground level with the temperature of the ice crystals. Ice can form in the atmosphere at any time of the year at that latitude.

Sounds like a sun dogs; works like a sun dogs. Tiny prisms of ice are suspended in the air, and the wind blowing horizontally aligns the crystals long axis horizontally. These prisms refract the light above and below the light source. This looks like vertical columns of light above (and below) each source.

The ligth from the pillar just above the lightsource is reflected from a spot just above the light source, so there has to be ice at a very low altitude.
