I calculate Boston sunset at around 2235Z (and sunrise at 1035Z) for the last
week of September, so there is a very small amount of darkness overlap.
Nonetheless, I agree that this is a very marginal, if not impossible, path for
W1 at that time of the year.
If my experience with Zone 23 on 80m is any guide, the winter months are much
better, but still pretty marginal. Over the years I've had a number of Zone 23
QSOs there, split roughly 50/50 between our sunset and our sunrise. The
sunrise openings occurred in December/January and were over the SW long path.
The sunset openings occurred from January through March, when there is a lot of
darkness overlap, over the SE skewed long path. The best Zone 23 opening I
ever observed on 80 was around the spring equinox.
