Eclipse Duration is the duration of the partial phase of a partial eclipse.įor total eclipses two values are given. The fraction of the Moon's diameter obscured by Earth's umbral shadow at the instant of greatest eclipse.įor total eclipses, the umbral magnitude is always greater than or equal to 1.įor partial eclipses, the umbral magnitude is always greater than 0 and less than 1.įor penumbral eclipses, the umbral magnitude is always negative (i.e., less than 0). The distance between the axis of Earth's umbral shadow and the center of the Moon's disk reaches a minimum. Geographic abbreviations (used above): n = north, s = south, e = east, w = west, c = central The Key to Lunar Eclipse Decade Table contains a more detailed description of each item in the table.įor more data on lunar eclipses during this period, seeĪmericas, n Europe, e Asia, Australia, PacificĮ Americas, Europe, Africa, Asia, Australia The equidistant cylindrical projection map below illustrates the geographpic region of visibility for each phase of the eclipse.Įach figure is stored as a PDF file of about 110 kilobytes.Īll eclipses belonging to a particular Saros Series are listed in a table linked through the Saros number. The top diagram shows the Moon's trajectory with respect to Earth's penumbral and umbral shadows. Two fields in the summary table provide links to graphics and additional information for each eclipse.Ī figure consisting of a diagram and map for each eclipse may be seen by clicking on the Calendar Date. The second value (in bold) is the duration the total phase.įinally, the Geographic Region of Eclipse Visibility provides a brief description of the regions where each eclipse will be seen. The first is the interval between the beginning and end of the partial phases. If the eclipse is total then two durations are listed. The Eclipse Duration gives the length of the partial eclipse. The Umbral Magnitude (column 5) gives the fraction of the Moon's diameter immersed in Earth's umbral shadow at the instant of greatest eclipse. The third column lists the Eclipse Type which is either Total, Partial, or Penumbral.Įclipses recur over the Saros cycle, a period of approximately 18 years 11 days.Įach eclipse belongs to the Saros Series shown in the 4th column. The second column TD of Greatest Eclipse is the Terrestrial Dynamical Time of greatest eclipse. The first column gives the Calendar Date of the instant of greatest eclipse. © 2023 NYP Holdings, Inc.A concise summary of all lunar eclipses from Just before the eclipse peaks - or when the sun and moon are in perfect opposition - light that normally reflects directly off the lunar surface will be redirected through Earth’s atmosphere, filtering out the blues of the UV spectrum so that only the reds and oranges remain - hence the changing effect.Īnd, the bigger the moon appears, the more dramatic the show. VCG via Getty Images What is the meaning of “blood moon”?Ī blood moon occurs only during a lunar eclipse and emits an orange-red glow during its several minutes of transit through Earth’s shadow, due to an optical illusion caused by our atmosphere. May 15 marks this season’s total “super flower blood moon” eclipse - when the gleaming full moon in the spring casts an eerie red glow during an eclipse. That’s where its other grisly nickname comes in. Some astro-forecasters say that Sunday brings more of a semi-super moon - as there’s an ongoing debate in the scientific community about the true definition - which still makes for a pretty spectacular eclipse portion of the Americas, Antarctica, Europe, Africa and the East Pacific. Skywatchers know that a moon is “super” when its orbit reaches one of its closest points to Earth - also called “in perigee” (and the opposite of which, “in apogee,” means the moon is at its furthest). But this one’s extra special - because it’s also the first of two lunar eclipses in 2022, and slated to be a big one. May 15 marks this season’s full “flower moon,” historically occurring around the time flowers are in full bloom for spring in North America, according to the Farmer’s Almanac. The blood moon rises tonight - and briefly disappears.
