Smoke Haze.

 Melbourne is experiencing a very warm, windless and dry Autumn, which combined with the beginning of the burning off before winter season, is producing smoke haze throughout the day. Walking through the park this morning, I noticed the rays of the sun shining on to the ground through the smoky air.

I didn't have the camera looking directly into the sun, but the rays bounced off the branch and produced this rainbow flare, almost like a comet with a tail. Click the picture to enlarge and you can see the colours.
