About two hours before the umbral shadow touches down in Europe, where is the most advantage continent for this eclipse, northeast of North America will experience a partial eclipse during sunrise. In much of this region the eclipse is already going on when the Sun emerges from eastern horizon. Partial eclipse lasts only a few tens of minutes or less from sunrise until the Sun coming back to be the full disk. Partial eclipses at maximum stage as seen from selected cities in the region. The eclipsed-Sun disks are related to local horizon.
All times are local daylight time.
If the sky is clear enough, observers in Boston will see a rising eclipsed-Sun on the morning of August 11th. In the US, only parts of the nation in northeast will see a partial eclipse. It can be seen only from NE of a line that curves from northwestern Pensylvania to the Atlantic coast around Virginia-North Carolina border. There are no place where the partial eclipse lasts longer than an hour. Boston and surrounding area might be a best place to waiting for a crescent Sun at dawn.
