The Watchers, 6/19/13, Chiffre
Planet Jupiter began the month of June 2013 being positioned very low in the west sky just after sunset. However soon it will disappear into the solar glare, as Jupiter is approaching the Sun for a solar conjunction on June 19, 2013. At that time Jupiter will pass behind the Sun, an event that happens about every thirteen months.
Because Jupiter`s orbit is somewhat ecliptic, it often passes either slightly above or below the Sun, when observed from our planet. Interestingly, on June 19, 2013, Jupiter will pass directly behind the solar disk and get totally obscured by the Sun, which occurs only twice within the planet`s 12-year orbit around the Sun
