Time lapse plan

So we want to get our time lapse going from night to day in Trafalgar Square, this means we are going to have to aim to be on trafalgar by 5:30-6am as the sunrises shortly after 6, we've discussed when would be good to go shoot it as we want to get it soon so we are going to hopefully go Friday morning and capture our time lapse, fingers crossed the weathers good!! It is supposed to be!
