March 1988 lunar eclipse
A penumbral lunar eclipse took place on Thursday, March 3, 1988, the first of two lunar eclipses in 1988, the second being on August 27, 1988.[1] Earlier sources compute this as a 0.3% partial eclipse lasting under 14 minutes, and newest calculations list it as a penumbral eclipse that never enters the umbral shadow. In a rare total penumbral eclipse, the entire Moon was partially shaded by the Earth (though none of it was in complete shadow), and the shading across the Moon should have been quite visible at maximum eclipse. The penumbral phase lasted for 4 hours, 53 minutes and 50.6 seconds in all, though for most of it, the eclipse was extremely difficult or impossible to see. The Moon was 2.2 days after apogee (Apogee on Tuesday, March 1, 1988), making it 6.1% smaller than average.[2] This was a relatively rare total penumbral lunar eclipse with the moon passing entirely within the penumbral shadow without entering the darker umbral shadow. The tables below contain detailed predictions and additional information on the Penumbral Lunar Eclipse of 3 March 1988.Penumbral Magnitude: 1.09076 Umbral Magnitude: -0.00163 Gamma: 0.98855 Saros Series: 113th (62 of 71) Date: 3 March 1988 Greatest Eclipse: 03 Mar 1988 16:12:45.7 UTC (16:13:41.5 TD) Ecliptic Opposition: 03 Mar 1988 16:01:03.9 UTC (16:01:59.8 TD) Equatorial Opposition: 03 Mar 1988 15:09:41.3 UTC (15:10:37.2 TD)
VisibilityThe total penumbral lunar eclipse was visible over Europe, Africa, Asia, Australia, northwestern North America, seen rising over the 30th meridian east and setting over the 150th meridian west on the Equator.
Relations to other lunar eclipsesEclipses of 1988
Saros seriesThis eclipse is part of Saros cycle series 113. Lunar year series
Metonic seriesThe Metonic cycle repeats nearly exactly every 19 years and represents a Saros cycle plus one lunar year. Because it occurs on the same calendar date, the Earth's shadow will be in nearly the same location relative to the background stars.
Half-Saros cycleA lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[3] This lunar eclipse is related to two total solar eclipses of Solar Saros 120.
