Look East
It rises at 9:16 PM and reaches 18° above the horizon at its best.
Just look up
Face east after dark. The Moon is unmissable; watch the terminator (the line between light and shadow), where crater shadows are sharpest.
Grab binoculars
Steady 10×50 binoculars reveal the dark maria (the “seas”) and bright crater rays splashing across the surface.
Any telescope shines
Even a small scope shows craters in 3-D relief along the terminator. Try 50–100× and trace the shadow line.
Aim along the terminator: the line where lunar night meets day. The sun sits low there, casting long shadows that make craters stand out in sharp relief. Near the bright limb, look for brilliant rays splashing out of the younger craters.
Ask your kid to find the “rabbit” or a friendly face hiding in the Moon's dark patches.
SKY DARKNESS
Bortle 9Bright inner-city sky: expect only the Moon, planets, and a handful of the very brightest stars. The Moon, planets and the ISS shine right through city glow.

Common questions
Where exactly should I look?
Face east and look low near the horizon; an open view without buildings or trees helps. The Moon reaches 18° altitude around 10:57 PM from San Jose, CA.

Do I need a telescope?
No. At 82% lit the Moon is a stunning naked-eye sight. Binoculars reveal the dark “seas,” and any small telescope shows craters in dramatic relief along the shadow line.
Will clouds get in the way?
