# March 2006 lunar eclipse

A penumbral lunar eclipse occurred at the Moon’s descending node of orbit on Tuesday, March 14, 2006, with an umbral magnitude of −0.0584. It was a relatively rare total penumbral lunar eclipse, with the Moon passing entirely within the penumbral shadow without entering the darker umbral shadow. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A penumbral lunar eclipse occurs when part or all of the Moon's near side passes into the Earth's penumbra. Unlike a solar eclipse, which can only be viewed from a relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of Earth. Occurring about 2.2 days after apogee (on March 12, 2006, at 20:45 UTC), the Moon's apparent diameter was smaller.

## Visibility

The eclipse was completely visible much of Africa, eastern South America, Europe, and west Asia, seen rising over North and South America and setting over much of Asia and western Australia.

## Eclipse season

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.
Eclipse season of March 2006 :
| March 14 Descending node (full moon) | March 29 Ascending node (new moon) |
| Penumbral lunar eclipse Lunar Saros 113 | Total solar eclipse Solar Saros 139 |

### Lunar eclipses of 2006–2009

This eclipse is a member of a semester series. An eclipse in a semester series of lunar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.
The lunar eclipses on July 7, 2009 (penumbral) and December 31, 2009 (partial) occur in the next lunar year eclipse set.

### 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 in nearly the same location relative to the background stars.

### Saros 113

This eclipse is a part of Saros series 113, repeating every 18 years, 11 days, and containing 71 events. The series started with a penumbral lunar eclipse on April 29, 888 AD. It contains partial eclipses from July 14, 1014 through March 10, 1411; total eclipses from March 20, 1429 through August 7, 1645; and a second set of partial eclipses from August 18, 1663 through February 21, 1970. The series ends at member 71 as a penumbral eclipse on June 10, 2150.
The longest duration of totality was produced by member 38 at 103 minutes, 6 seconds on June 5, 1555. All eclipses in this series occur at the Moon’s descending node of orbit.

### Tritos series

This eclipse is a part of a tritos cycle, repeating at alternating nodes every 135 synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee), but groupings of 3 tritos cycles (≈ 33 years minus 3 months) come close (≈ 434.044 anomalistic months), so eclipses are similar in these groupings.

### Inex series

This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings.

### Half-Saros cycle

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros). This lunar eclipse is related to two total solar eclipses of Solar Saros 120.
