Of course you can put in in your logbook. And you should! Get somebody to take some pictures and stick those in as well.
It is your logbook, and since it is not a safety issue whether you put it in or not I am sure the CAA couldn't care less.
Having said all that, just remember it doesn't count for anything.
You need to fly these things 'by the numbers'. Your instructor will provide these numbers. Stick to them, and it will all work out fine.
Most importantly, enjoy!
