Late on Monday evening and early Tuesday morning, Apr. 14-15, the shadow of the Earth slowly moves across the Moon, making a total eclipse of the Moon, be visible from throughout the U.S. The Earth’s shadow is always cast into space and is in the opposite side of the sky from where the Sun is. So lunar eclipse happens when the full Moon and the Sun are exactly opposite each other in our skies and the Earth moves between them. The eclipsed Moon will be high in the sky and easily visible (provided it’s not cloudy). The moon will appear strange in the sky—sunlight refracted by the earth’s atmosphere and falling upon the moon will make it red or orange in color. Watch with naked eye, binoculars, and/or telescope.
Near sunset - Moon rises
9:54 pm PDT - Moon enters Earth's outer shadow (penumbra)—not too noticeable
10:58 pm PDT - Partial eclipse starts—Moon enters Earth’s inner shadow (umbra)
12:07 am PDT - Total eclipse starts—
Moon fully inside Earth's inner shadow
12:46 am PDT - Mid-eclipse
1:25 am PDT - Total eclipse ends—Moon no longer fully inside Earth's inner shadow
2:33 am PDT - Partial eclipse ends—Moon completely exits Earth’s inner shadow
Chabot Space and Science Center - Special open evening for the Total Lunar Eclipse at Chabot Space and Science Center http://www.chabotspace.org/
Lawrence Hall of Science - Total Lunar Eclipse event at Lawrence Hall of Science.
Monday, April 14
11:00 p.m.–1:30 a.m. (runs into morning of April 15)
$10 General Admission, $5 Members
4 elements to the Lawrence Hall of Science party:
---Look through astronomical telescopes to observe the first total lunar eclipse visible in the Bay Area since 2011
---Drop-in Planetarium open house where you can explore times when eclipses happen, and get intriguing different views of of eclipses (as seen from the Earth, from space, from the Moon, from above looking down, and from the bottom looking up), see and model phases of the Moon. Also see a magnificent 3D modeling of Earth's shadow, which is the real culprit responsible for causing the lunar eclipse.
---Drop-in Science-on-a-Sphere open house where you can see where on Earth the eclipse is visible, what the eclipse looks like from Earth orbiting satellites, and exact times when the different stages of eclipses begin and end.
---Lunar eclipse activity/game area where you can:
- test your skill at creating and accurate, to-scale model of lunar eclipses,
- set up a model that shows that the celestial conditions conducive eclipses occur every 6 months
- computer simulations
- make and eat an oreo cookie model of lunar phases or eclipses.
The San Jose Astronomical Association (SJAA) will host an eclipse party, Houge Park; see

Colfax. Local astronomers will be setting up telescopes at the Auburn Dam Overlook to provide free views of the eclipsed moon, Jupiter, Mars and Saturn, if the weather is permitting. We will be there from 11:00 PM until 1:30 AM. The viewing is free and dependent upon the weather. If it is overcast
or raining the public event is cancelled, but the eclipse will still go
on. To get to the Overlook, go to downtown Auburn, to the historic
Courthouse. One of the roads branching from there is Auburn-Folsom Rd.
Take that to the third stoplight (about 0.8 mile). This is Pacific
Ave. Turn left at this stoplight and go about 0.6 miles to the American
River Overlook, which is on your right. We are at the far end of the
parking lot. -Don Machholz
The northern part of the Moon is closer
to the center of the shadow and therefore darker.
On most months, the Moon travels north of south of the shadow. Once or twice a year the Moon passes through the shadow, when this happens it dims and takes on an unusual red hue. This can be seen from anyone who can see the Moon, that is, half of the earth’s population.
