Transit should occur somewhere between 0 and 1 UT June 6, 2116. Nominal declination of the Sun 22d 40.2', Venus 22d 50.2'. So the question becomes, how large can the difference of declinations be when GHA is identical and still be termed conjunction? On the flip side of the coin, if declinations are identical, how large a difference in GHA is allowable? Bill
