Partial Lunar Eclipse on June 4th, 2012
Everyone keep an eye out for this cool event. It will be visible on the morning of June 4 for North America, but in Australia and Asia it will be the evening June 4. Approximately one third of the moon’s face will be eclipsed. For us here in NZ it will start at 10:00pm, keep an eye out! I know I will.

This eclipse will largely be an event for the Pacific and Australasia, although the Americas will be able to see some part of it. Information and times for various locations can be found here, here, and here.
On (And Near) The Center-Line: The 20th May annular solar eclipse from Utah
Kanarraville, Utah was very close to the center-line of Sunday’s eclipse, meaning that it was nearest to the center of the darkest shadow cone produced by the Moon as it crossed the face of the Sun. In this image, the disk of the Sun (red) perfectly frames the shadowed outline of the Moon at mid-eclipse. Compare with the photo below, taken from Zion National Park (about 18 miles southeast of Kanarraville) at the same time.

The location of the two sites is shown on the map below. The red line is the eclipse center-line; Kanarraville is very close to where the red line crosses the thick orange line indicating Interstate 15. Zion is at bottom-center.
Even though the moon is about 240,000 miles away, a linear difference of 18 miles on the surface of the Earth is sufficient to noticeably shift the apparent position of the Moon in the sky. This becomes crucial in total solar eclipses, when the region in which the eclipse is total may be only a few miles in width.
Annular eclipses occur when the Moon is slightly further away from the Earth than on average; when it is closer than average, the solar disk is completely blocked and a total eclipse occurs. The next annular eclipse is on May 10, 2013.
