Found another possibility if it doesn't have to be a technical occultation. On 28th January 1805 Venus and the Moon are within 2.4 degrees of each other before dawn at approx 5:40am and visible from the indian ocean (I picked a spot at 69E 1N but it would be visible for a wide area).

This would be a very splendid site even if not an occultation.

I've made you an mpeg movie of this which will play in windows media player - it's 5MB so be prepared for a wait unless you have broadband. There are also 3 jpeg stills to show you the event rising above the horizon.

Have a look at;
