Enormous light covers northern horizon of Fort Worth TexasI had just had the vet out to check on one of my horses late one afternoon about 4:00 after a brief ice storm in the area.The vet left about 5 and i stayed with the horse until about 5:45 or so. I left the ranch and turned onto the service road of I 35 heading north. The clouds were dark but the sun was breaking trhough somewhat to the west,on my left.I noticed that it looked like the sun was also setting to the north as well! The entire northern horizon was lit up in a pale violet blue light. The light seemed to come down from the clouds and fan out over the horizon. The city of Fort Worth, Texas was directly under the light.I looked at the light for several seconds and then to my astonishment it simply turned off! The sky was entirely black in front of me! I was so shocked I immediatley drove home and turned on the TV expecting to see something on the news about it, but nothing.I am a teacher and mentioned it to my 5th grade class the next day to see if anyone else in Fort Worth had seen it and one student who is fairly level headed told me she and her mother had seen it while driving and didn't know what it was either.I know it was not lightening or some kind of power surge as the light was coming from above. It really scared me and it still does because it was huge!What ever it was it covered an entire section of the sky.((NUFORC Note: Source of report indicates that the date of the incident is approximate.
