Venus 

Ephemeris 2005-2015

Venus is visible for about 8 months before its greatest Eastern elongation date (evening apparition) and for a further 2 months afterwards, after which it disappears into the evening twilight. For morning apparitions, it is visible for about 2 months before its greatest Western elongation and for a further 8 months afterwards, following which it disappears into the morning twilight. Its greatest brilliance occurs about 5 weeks after greatest Eastern elongation (evening apparition) and about 5 weeks before greatest Western elongation (morning apparition).

In the following list, greatest elongation details are given in brackets in the format "Solar elongation, Constellation". Hence "45, Psc" means "45 from the Sun, in the constellation Pisces". Its elongation from the Sun at dates other than greatest elongation can be estimated on the basis that the angular elongation is 0 at inferior and superior conjunction (Venus typically remains close to its greatest elongation for about a week or two before and after the greatest elongation date).

Mercury 

Greatest Elongation Dates 2005-2015

Mercury is easiest to see when it reaches greatest elongation, however it can normally be seen for several days either side of this date. A flat, unobstructed horizon is required to see it. In the following list, details are given in the format "Solar elongation, Constellation, Favourable Viewing Hemisphere". Hence "21, Tau, NHem" means "21 from the Sun, in the constellation Taurus, best seen from the Northern Hemisphere". The constellation in which Mercury is located is rarely visible because of twilight, however it can be used as an aid in determining the direction in which to look for the planet (times of local sunrise, sunset and twilight can be obtained from Time and Date.com).
