Low Tides, a Waxing Crescent Moon, and Jupiter's Satellites

October's Lowest Tides, coinciding with afternoon hours several days in a row, usher in several months of excellent tidepooling opportunities. A -0.6 foot tide occurs at 3:34pm on the Thursday, October 7. A -0.8 foot tide occurs at 4:20pm on Friday, and a -0.7 foot tide occurs at 5:09pm on Saturday. The region's best-known places to view intertidal life include Cabrillo National Monument and various rocky stretches of coastline near La Jolla.

The Waxing Crescent Moon makes its first easily observed appearance in the evening sky on Sunday, October 10. At around 20 minutes after the time of sunset, look low in the southwestern sky, to the left of where the sun went down, and you will spot the moon's thin crescent shape. Unlike in the spring season when the evening crescent moon "smiles" with upturned cusps, the autumn crescent-moon cusps point well to the left -- toward the southern part of the sky.

Jupiter's Galilean Satellites, the four largest and brightest moons circling the planet, can be easily observed this month through the end of the year using equipment as simple as firmly supported, high-power binoculars. First observed by Galileo in 1610, these satellites noticeably change their configuration from night to night as they swing around the planet. First, of course, you must locate the planet itself in the sky. Jupiter is the brightest star-like object in the evening sky, located high above the east horizon on October evenings and shifting toward the southern sky by December
