light from sky came down in arc shape over horizonI reported this occurrence a while back and just now looked to see if it was in your reports for February. I noticed the report date was there but no report.I am hoping you don't think it was a hoax.I am still stunned by the sighting. It was truly shocking to see! Driving north on the service road of I35 toward Fort worth Texas at dusk after an ice storm, the northern sky was lighted from above in an arc shape to the ground covering a good portion of the sky. It stayed that way for several seconds(it was lit up as soon as I turned on to the service road) and suddenly as if someone turned off a switch, it completely turned off. The sky was then dark. I know it was not lightening or anything like that. It was so incredibly unusual that it really scared me.
