Incredible sunrise during a time-lapse session

During a time-lapse a two weeks ago I experienced the most astounding sunrise yet.  I had set my camera, and the rest of the equipment including the coffee flask in place to be handy.  Whilst sipping my coffee slowly I realised the sky was changing from a blur to a set of netted lines.  So down went the coffee I fetched the EOS20D since the 5D was already shooting an array of 700 shots every ten seconds. got the 18/55 and wondered off keeping an eye on my equipment in solitude.

This is the result. An incredible sunrise I must say.
