Can lunar occultation of Venus occur during solar eclipse? Moon can occult Venus. Venus can transit across the solar disc. Moon can elipse Sun. Can all three celestial events occur at the same time - Moon is at front of Sun (partial eclipse is fine) and Venus is behind Moon (ideally part of the planets is seen at lunar limb)? Observer is at Earth.
Yes, but such an event would be very rare. Venusian transits last only about 7 hours, and there are only two in 113 years, So Venus is in transit for about 0.0015% of the time.

So as a back-of-the-envelope calculation, you would need to see about 70000 eclipses before you had a combined transit/eclipse.  There are about 2 solar eclipses a year, so you might hope to get this unusual syzygy once every 35000 years or so.

None are forecast.
