</p><p>Here's what green flash specialist <a rel="nofollow" class="external text" href="http://mintaka.sdsu.edu/GF/">Andy Young</a> writes about the sequence:
</p>
"One of <a rel="nofollow" class="external text" href="https://sites.google.com/site/thebrockeninglory/">Brocken Inaglory</a>'s green flash pictures. She has been collecting flashes since late 2005 in San Francisco. This one turns out to be a little more complicated than a simple inferior-mirage flash (I've seen her other frames of this sunset).<br>Notice the gradation in color within the flash: yellowish in the center, bluish at the extreme ends. This picture also shows the effect of atmospheric reddening well in the prominent contrail. The orangish hue of the sky, and the visibility of blue in the flash, are indications of extremely clear air.<br>In addition, there's a small cloud beyond the horizon, miraged by the same layers near the sea surface that stretch the normally invisible green rim into a green flash. It's to the left of the flash, and about the same size; notice that it's exactly the same height above the horizon as the flash."
