Graphic of the Event http://sunearth.gsfc.nasa.gov/eclipse/SEplot/SE2000Dec25P.gif 2000 Dec 25: Partial Solar Eclipse The final eclipse of the Second Millennium is a partial solar eclipse on Christmas day. Fortunately, the event will be well placed for observers throughout most of North America (Figure 7). First and last penumbral contacts occur at 15:26:37 UT and 19:43:12 UT, respectively. Greatest eclipse 1 occurs at 17:34:51 UT with a maximum eclipse magnitude of 0.7231 from Baffin Island. Most of North America will witness the event with the exception of northwestern Canada and Alaska. A detailed map (Figure 8) can be used for estimating eclipse magnitudes and Universal Time of maximum eclipse for locations throughout the continent. Local circumstances (in Universal Time) for a number of cities are given in Table 4. Sun's altitude and azimuth, the eclipse magnitude and obscuration are all given at the instant of maximum eclipse. This event is the fifty-seventh eclipse of Saros series 122. The last central eclipse of the series was annular and occurred in 1874. The series ends with a partial eclipse in 2235. An animation shows the motion of the Moon's shadow across Earth's surface (courtesy of Dr. Andrew Sinclair). 1The instant of greatest eclipse occurs when the distance between the Moon's shadow axis and Earth's geocenter reaches a minimum. Although greatest eclipse differs slightly from the instants of greatest magnitude and greatest duration (for total eclipses), the differences are usually quite small. 2Minimum distance of the Moon's shadow axis from Earth's center in units of equatorial Earth radii.
