There will be a very close conjunction of the Moon and Mercury this evening. A very thin moon, only 4% illuminated will pass the planet at a mere 42 arc-minutes separation. Taking into account the 30 arc-minute diameter of the Moon will leave Mercury less than 30 arc-minutes from the limb of the Moon. Mercury will be shining brightly at -0.2 magnitude, a nice match for the very young Moon. The pair will be about 15° above the horizon at sunset, allowing an excellent view of the conjunction.
