Nacreous Clouds

First guest post!
Or, perhaps, a reblog, but I asked her if I could link it as a guest post.

Last year, I posted a few pictures of this dazzling phenomenon I observed in the sky.

A year later, thanks to the Collins Weather Wild Guide, I have learned that what I saw were nacreous clouds, a form of iridescence.

Something I already knew: Nacreous clouds are rare, and I was very lucky to observe them.

Thanks to my longtime friend Chu_Hi on Livejournal, who wrote all of this, and took this photos from one of the giant planes in which she spends much of her waking hours. This is her photo, please don't use it without her permission.

As much as it's been hard for me to keep up with this blog all year, for no good reason, it might get harder soon as we have a baby joining our family for good in mid-March, and I'm going to be spending available time parenting for the next 18 years or so. I'm going to continue to try to maintain at least my current level of blogging, but if you're willing to toss a guest-blog post at me now and then, let me know -- geographile at -- and we can talk.
