A waxing crescent moon if skies are clear

21/08 sunset Carhaix 22:21 (this is where I got to last time on the Monday, and my start time is similar)
22/08 Sunrise Brest 07:22 (not sure if this will be relevant to leaving Brest or arriving at Brest)
Beyond that, plans may go out the window due to weather, control queues, amount of drafting available.
