NASA Jet Propulsion Laboratory California Institute of Technology Evaluating a Lunar Eclipse The Danjon Scale of Lunar Eclipse Brightness illustrates the range of colors and brightness the Moon can take on during a total lunar eclipse and is a useful tool to observers in characterizing the appearance of an eclipse. The evaluation is best done with the naked eye, binoculars or a small telescope near the time of mid-totality. It is also helpful to examine the Moon's appearance just after the beginning and just before the end of totality. In making evaluations, the instrumentation and the time must also be recorded. Use the following scale to assign an "L" value at three points during the eclipse. Consider taking a picture of the Moon to provide evidence for your evaluation. • • • • L = 0 Very dark eclipse (Moon is almost invisible, especially at mid-totality) L = 1 Dark eclipse, gray or brownish in coloration (Details are distinguishable only with difficulty) L = 2 Deep red or rust-colored eclipse (Very dark central shadow, while outer umbra is relatively bright) L = 3 Brick-red eclipse (Umbral shadow usually has a bright or yellow rim) L = 4 Very bright copper-red or orange eclipse (Umbral shadow has a bluish, very bright rim) Just after totality begins Time: Instrumentation (circle one): telescope / binoculars / naked-eye L = Moment of greatest eclipse Time: Instrumentation (circle one): telescope / binoculars / naked-eye L = Just before totality ends Time: Instrumentation (circle one): telescope / binoculars / naked-eye L = NASA/JPL Education - Evaluating a Lunar Eclipse Discover more: www.jpl.nasa.gov/edu Calendar Date TD of Greatest Eclipse Type Saros Series Umbral Eclipse Magnitude Duration Lunar Eclipses: 2021 - 2030 Geographic Region of Eclipse Visibility Eclipse 2021 May 26 11:19:53 Total 121 1.009 03h07m 00h15m e Asia, Australia, Pacific, Americas 2021 Nov 19 09:04:06 Partial 126 0.974 03h28m Americas, n Europe, e Asia, Australia, Pacific Americas, Europe, Africa 2022 May 16 04:12:42 Total 131 1.414 03h27m 01h25m 2022 Nov 08 11:00:22 Total 136 1.359 03h40m Asia, Australia, Pacific, Americas 01h25m 2023 May 05 17:24:05 Penumbral 141 -0.046 Africa, Asia, Australia 2023 Oct 28 20:15:18 Partial 146 0.122 01h17m e Americas, Europe, Africa, Asia, Australia 2024 Mar 25 07:13:59 Penumbral 113 -0.132 2024 Sep 18 02:45:25 Partial 118 0.085 01h03m Americas Americas, Europe, Africa 2025 Mar 14 06:59:56 Total 123 1.178 03h38m Pacific, Americas, w Europe, w Africa 01h05m 2025 Sep 07 18:12:58 Total 128 1.362 2026 Mar 03 11:34:52 Total 133 1.151 2026 Aug 28 04:14:04 Partial 138 0.930 03h29m 01h22m 03h27m 00h58m 03h18m Europe, Africa, Asia, Australia e Asia, Australia, Pacific, Americas 2027 Feb 20 2027 Jul 18 2027 Aug 17 23:14:06 Penumbral 143 -0.057 16:04:09 Penumbral 110 -1.068 07:14:59 Penumbral 148 -0.525 2028 Jan 12 04:14:13 Partial 115 0.066 00h56m e Pacific, Americas, Europe, Africa Americas, Europe, Africa, Asia e Africa, Asia, Australia, Pacific Pacific, Americas Americas, Europe, Africa 2028 Jul 06 18:20:57 Partial 120 0.389 02h21m Europe, Africa, Asia, Australia 2028 Dec 31 16:53:15 Total 125 1.246 03h29m Europe, Africa, Asia, Australia, Pacific 01h11m 2029 Jun 26 03:23:22 Total 130 1.844 03h40m Americas, Europe, Africa, Mid East 01h42m 2029 Dec 20 22:43:12 Total 135 1.117 03h33m Americas, Europe, Africa, Asia 00h54m 2030 Jun 15 18:34:34 Partial 140 2030 Dec 09 22:28:51 Penumbral 145 0.502 -0.163 02h24m Europe, Africa, Asia, Australia Americas, Europe, Africa, Asia Geographic abbreviations (used above): n = north, s = south, e = east, w = west, c = central [ 1 ] Greatest Eclipse is the instant when the distance between the axis of Earth's umbral shadow and the center of the Moon's disk reaches a minimum. [2] Umbral magnitude is the fraction of the Moon's diameter obscured by Earth's umbral shadow at the instant of greatest eclipse. For total eclipses, the umbral magnitude is always greater than or equal to 1. For partial eclipses, the umbral magnitude is always greater than 0 and less than 1. For penumbral eclipses, the umbral magnitude is always negative (i.e., less than 0). [3] Eclipse Duration is the duration of the partial phase of a partial eclipse. For total eclipses two values are given. The first is the period between the beginning and end of the partial phases, while the second value (in bold is the duration of the total phase. [4] Geographic Region of Eclipse Visibility is the portion of Earth's surface where some portion of the eclipse can be seen.
