March 1988 lunar eclipse

A penumbral lunar eclipse took place on March 3, 1988, the first of two lunar eclipses in 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.[2]

The entire moon passed through the penumbral shadow during this eclipse. It grazed the northern edge of the Earth's umbral shadow, but not sufficiently to qualify a partial eclipse.

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.

Relations to other lunar eclipses

Eclipses of 1988

Saros series

This eclipse is part of Saros cycle series 113.

Lunar year series

Metonic series

The 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.

  1. 1988 Mar 03.675 – Partial (113)
  2. 2007 Mar 03.972 – Total (123)
  3. 2026 Mar 03.481 – Total (133)
  4. 2045 Mar 03.320 – Penumbral (143)
  1. 1988 Aug 27.461 – partial (118)
  2. 2007 Aug 28.442 – total (128)
  3. 2026 Aug 28.175 – partial (138)
  4. 2045 Aug 27.578 – penumbral (148)

Half-Saros cycle

A 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.
