This will be a rare opportunity to spot elusive Mercury, normally hidden by its proximity to the Sun.
Astrologically, such a conjunction bodes well for communication, business, talks and seminars, teaching, writing and networking. A great time for a party too!

Although Jupiter will cease to be visible at the end of May (becoming 'under the sunbeams') it will continue to be a good time to spot Mercury up to the middle of June. Just find Venus visibly bright and then look up about 45° to the left. The optimum date is round about 8th. June.
Mercury, Venus and the Sun have appeared to overtake Jupiter very quickly - it's because of the perspective, Jupiter being so much farther away. Distances at beginning of June : Mercury 98m miles, Venus 151m miles, Jupiter 566m miles. Mercury is dimmer because it is a lot smaller, Venus especially bright because it is covered with pale clouds which coupled with its closeness to the Sun make it very reflective of light ("high albedo"). Jupiter can at times be almost as bright as Venus despite its distance, because it is so large.
