Another day at sea,
and the air has cleared a bit, giving way to clearish skies, perfect for
capturing the disc of the sun dipping into the horizon. As a result, please
enjoy an image of sunspots, one version straight from the camera, the other viewed
showing the mask of a sharpening algorithm, which illustrates quite plainly the
locations of them on the surface of the sun. Sunspots can last for days or
weeks (I believe), the larger of which can contribute to radio communications
interference here on earth. Several years ago I experienced a significant solar
radiation event while flying around Denver, and for a few days reaching
hospitals on routinely-used VHF frequencies was marginal, at best.
Enjoy.
