At around 8.10pm, December 18th 2015, I was driving home from work, ans pulled over to make a phone call, when I noticed a short, crisp contrail in the dusk sky, in Magellan Street, Lismore. I took one quick photo, not noticing until I uploaded the photo to my laptop, that a horizontally aligned disc was above right of the contrail. I t is a bit blurry & hazy in appearance, like a smallish cloud (it was a clear crisp dusk sky). When I zoomed in on it, it shows up to be a saucer shaped disc with a domed top in the centre of the disc shape.I put the photos on my social media page, only to be mocked and ridiculed, and told it was a hoax I made in Photoshop.
