Solar eclipse of February 7, 2008
Template:Short description Script error: No such module "Solar eclipse". An annular solar eclipse occurred at the Moon's ascending node of orbit on Thursday, February 7, 2008,[1][2] with a magnitude of 0.965. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. The Moon's apparent diameter was near the average diameter because it occurred 7 days after apogee (on January 31, 2008, at 4:25 UTC) and 6.9 days before perigee (on February 14, 2008, at 1:00 UTC).[3]
The moon's apparent diameter was 1 arcminute, 17.8 arcseconds (77.8 arcseconds) smaller than the August 1, 2008 total solar eclipse.
Visibility
Centrality was visible from parts of Antarctica. A significant partial eclipse was visible over New Zealand and a minor partial eclipse was seen from southeastern Australia and much of Oceania.
For most solar eclipses the path of centrality moves eastwards. In this case the path moved west round Antarctica and then north.
Observations
The best land-based visibility outside of Antarctica was from New Zealand. Professional astronomer and eclipse-chaser Jay Pasachoff observed it from Nelson, New Zealand, 60% coverage, under perfect weather.[4][5]

Eclipse season
Script error: No such module "Labelled list hatnote". This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight.

Solar eclipses of 2008–2011
This eclipse is a member of a semester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.[7]
The partial solar eclipses on June 1, 2011 and November 25, 2011 occur in the next lunar year eclipse set.

Metonic series
The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles. Eclipses occur in nearly the same calendar date. In addition, the octon subseries repeats 1/5 of that or every 3.8 years (1387.94 days). All eclipses in this table occur at the Moon's ascending node.
