The sun rises this week at the east end of Baltimore's original east-west street grid. If the streets pointed due east, this would occur on Sept. 23 - the autumnal equinox. But "street corner astronomer" Herman Heyn says early surveyors, using magnetic north instead of true north, skewed the grid 3 degrees counterclockwise. So our street-canyon sunrises are early - Sept. 18-19 - and sunsets are late - Sept. 29-30. Either is a blinding nuisance for downtown drivers, but an opportunity for shutterbugs.
