When is Sunrise in May?

Early, early start for our filming crew. We wanted to get a sunrise shot over London in a time-lapse and this required us to roll out of bed at 4am in order to travel to location and set up our shots. It was a huge sacrifice of personal comfort with an admittedly shallow payoff as it was very over-cast this morning. We got a very usable light change, but we missed the sun completely. We also got chased off the riverside for supposedly filming on private property, we got all the footage we needed before then though so we played dumb and just moved on. Driving back home there were many tired faces in the car, mine included. Looking forward to an early night tonight to recover. The coming days will be fraught with some late nights so I better prepare myself for some late ones.
