<blockquote><font class="small">In reply to:</font><hr /><p>I decided to post of few of my own "Sundog" images. I had called them "Sunbows" though.<p><hr /></p></p></blockquote><br /><br />Living in Minnesota, I get to see a lot of these sorts of effects; we have a nice long winter, part of which strikes during our dry period, which means there aren't clouds in the way. I've seen some spectacular effects.<br /><br />What you have a picture of there, NEVERS, is actually not a sundog. It's the 22 deg halo. This is a full halo going all the way around the Sun. It's usually iridescent like a rainbow. Sundogs, also called false suns, are bright patches on the left and right sides of the halo. Sometimes the sundogs will be visible but the halo will not, and vice versa; they are caused by different ice crystal shapes and alignments. I think the idea is that they're Apollo's hunting hounds or something like that.<br /><br />The Moon will also produce halos, and moondogs as well. It is not generally bright enough to produce the sun's more exotic effects, however.<br /><br />What's really weird is if you get to see one of the effects around the antisolar point. Glories are neat too; next time you're in an airplane during the day, see if you can see the airplane's shadow. If you're lucky, and it's being cast on clouds, you might see an iridescent halo around it! <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em> -- The Tenth Doctor, "Blink"</font></p> </div>
