    The evening “star” all summer, in the constellation Virgo, is Jupiter. Much dimmer is Saturn, visible in the southern sky between Sagittarius (the Teapot) and the head of Scorpio. The moon passes very close to Jupiter the evening of June 2, and close to Saturn on September 26.

    Mars is sinking into the sunset as June begins, return in the morning as September ends. Venus is high in the morning sky but sinks daily toward the sunrise. Venus and Mars shake hand on October 5 as they pass in the morning sky – Mars headed up, and Venus sinking into the morning glare.

    We invite you to join us for stargazing on Saturday, October 14 and Saturday, November 18 at 7:30 behind the Lutheran Church. (Details in the Calendar listing)

    Orionids on October 21, and the Leonids on November 16/17 are both close to new moon and thus enjoy perfect conditions for viewing. After midnight rates of 20 and 15 per hour, respectively, can be expected. But strays can appear October 4 to14 and November 5 to 30.

    A great opportunity to view the Orionids is at the annual Nightfall Star Party of the Riverside Astronomical Society. This group of avid and well-equipped star gazers will be at Palm Canyon Resort the weekend of Oct 19/22. Why not take a red flashlight, stroll around awhile and count meteors? Information is at nightfallstarparty.com.

    As Jupiter sets shortly after the sun in October, Saturn takes over as the bright “star” low in the Southwestern evening. Watch as it sinks behind the San Ysidro range earlier each night. Just after sunset on Monday November 20, watch for Saturn, a crescent moon and Mercury close together.

    Meanwhile, in the predawn an unusual pairing of red Mars and bright Venus can be spotted almost due East the hour before dawn during October. Watch October 5 when Venus seems to run into Mars, he headed up, and she down. Mars will remain visible, being the morning star in the east before dawn all of November.
