Saturday evening the just slightly past first-quarter Moon will come between Mars and Spica offering a great astro-photo opportunity. From certain parts of the world including the western coast of Central America west toward Hawaii observers will see the Moon occult, pass between us and the planet Mars sort of like an eclipse. The time for this is around 1 UT, which puts this event in the evening on 5 July for my time zone of Central Daylight (UT-5). From my latitude (38° 55.26′ N) and longitude (94° 20.922′ W) this will be a close conjunction as the Moon will be about 0.5o from Mars, and about 2.5o from Spica.
As this graphic shows it will be a great sight through binoculars. I included how the Moon and Mars would look/compare when viewed through my ancient 8″ Schmidt-Cassegrain Telescope with a 25mm eyepiece.
