What to do with the daylight
Aurora watching is a night job, and in winter that leaves a short, bright day to fill. Hässelby Villastad keeps its fortified past above ground, at Edsbergs Slott, Broby bro and Drottningholm Palace, and for a day when the cloud sits low, Tensta Konsthall, MC Collection and Orangeri-muséet are indoors and near by.
Keep the daylight loose: the sky decides the evening, and the forecast can turn within a few hours.
