When it caught my eye I was immediately aware that what I was seeing was something I have never seen before...it was bright electric greenish yellowish glowing arching ball of light..like a tennis ball overhand lob...it lasted for 3 to 4 seconds..and it just disappeared as if you turned off a lightbulb. No dimming...no subsiding or reducing.. Just an round alive arching bright green neon gassy light that seemed electic...vivid and immidatly attention grabbing.no trail.no tail..no trace..no shadow no flare no smoke no stream. Bam! it appeared...awe struck I was 4 seconds later...poof gone..dissaperared as it appeared. I was left in awe and dumbfounded at what I had witnessed. I KNEW IT WAS SOMETHING extremely BEAUTIFUL AND SOMETHING THAT WAS RARE.
