While I have a very few landscape images with sunbursts (sunflares, sunstars, pick your name…), one of my favorite activities is to get colored sunbursts in icicles. To get colored sunbursts, you have to find the few, very specific angles at which these can be seen. In this case, the icicle was formed by bright sunlight melting a dusting of snow on the leaves of a magnolia tree in my MD yard. Since the air temperature was below freezing the dripping water formed icicles. The two versions posted here occur because the leaf came to slightly different resting places after being moved by the breeze. That change in angle provides the different colors in the sunburst.
