Could it be? finally - a combo of factors that seem rarer than a venus transit, cloud cover predictions between 1-5% all night, windspeed 1-5km/h, Jetstream at 20-40kts, the waning crescent moon at 11.2% and rising at 4.30am.
Better free the schedule and prepare the thermos, though it seems like one night only!! Be there!
