|Nacreous clouds and Iridescence
||[Feb. 9th, 2011|08:06 am]
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.
