I’ve just started using the website Audioboo to upload short pieces of astronomy themed audio to the Web. My first ‘boo’ (as they’re called) is all about noctilucent clouds – the ethereal glowing clouds that appear in the northern hemisphere’s night skies around this time of year.

I’ve embedded the audio below. If you’d like to see some of my pictures from previous years’ displays you’ll find them here and here.
