Not an answer here, but there may be some helpful information in [this answer to *When are the planets occulted by the sun?*](https://astronomy.stackexchange.com/a/28263/7982) There's a GIF from SOHO images of the Pleides shooting past the Sun.

Can you add some numbers to your question? What is the Pleiades' ecliptic coordinates and what is the (mean) inclination of the Moon's orbit?

Could there be an eclipse tomorrow if the Pleiades is covered by the Moon tonight?

Consider how far the pleiades are above the ecliptic, and how far the moon travels in a day. From this you can work the angle at which the moon must travel relative to the ecliptic, in order to cross the eliptic within a day.

You can then compare this with the actual inclination of the moon's orbit to the ecliptic, and that will tell you if an eclipse is possible.
