The moon's orbit is inclined to the Earth's orbital plane by about five degrees, so the only time we get a solar eclipse is when the moon crosses the ecliptic (twice a month) AND the Sun happens to be in the same place! Thus they only occur a few times a year. Steve, didn't they teach you anything in GE103? Hari Nair han@cluster.gps.caltech.edu
