Is there a jig or a reel somewhere with the word “Noctilucent” in the title? 
I’m not sure people who play jigs and reels would want to use words like “noctilucent” in tune titles. Imagine trying to pronounce that after a few pints at the session.

Once I noctilucent tooth out.
You would just say “the one with that big word in the title” …
Over Sweden, huh? Hmm… I feel so depressed suddenly.
Here’s a pic of noctilucent clouds from my garden. They only appear in summer and you have to wait until the sun has set on all the much lower cirrus that may be around. Also, you need moonless conditions. There’s many a “noctilucent cloud” pic that really just shows ordinary cirrus lit up by the moon.
