The variation in the 3-cm emission of the moon during a lunation is very much less than the variation in the 8.6-mm emission, as would be expected from the explanation of Piddington and Minnett ( 1949 ).

Because the Julian calendar's implicit solar year has drifted further over the centuries than those of the Gregorian or Hebrew calendars, Julian Easter is a lunation later than Gregorian Easter in five years out of nineteen, namely years 3, 8, 11, 14, and 19 of the Christian cycle.

This means that it is a lunation later than Jewish Passover in two years out of nineteen, years 8 and 19 of the Christian cycle.

giving an error of only about half an hour in 687 years ( 2. 5 seconds a year ), although this is subject to secular variation in the length of the tropical year and the lunation.

This calculation makes use of a mean lunation length used by Ptolemy and handed down from Babylonians ( see Lunar_theory # Babylon ), which is still very accurate: ca.

The time interval between new moons — a lunation — is variable.

6h12m shorter, or + 0. 302d = 7h15m longer than average .< ref > This range is smaller than the difference between mean and true conjunction, because during one lunation the periodic terms cannot all change to their maximum opposite value.

* In ELP2000 – 85 ( see Chapront et alii 1988 ), D has a quadratic term of − 5. 8681 " T < sup > 2 </ sup >; expressed in lunations N, this yields a correction of + 87. 403N < sup > 2 </ sup > delay is − (− 5. 8681 ") / ( 60 × 60 × 360 "/ circle ) / ( 36525 / 29. 530 ... lunations per Julian century )< sup > 2 </ sup > × ( 29. 530 ... days / lunation ) days </ ref > days to the time of conjunction.

Moreover it is sufficient to keep track of just the numerator by adding once every lunation, an integer constant to a variable that is called the accumulator.

It doesn't show up in this chart, but when a lunation is skipped from a fumocy, it is phase 7 that is skipped, so that the associated adjustment of 0 is also skipped.

(*) Note that the computed lunation of 29 26 / 49 days is a bit too long, so an adjustment of 1 / 49 day must be made periodically to compensate.

One lunation ( an average lunar cycle ) is 29. 53 days.

However, the lunation is never more than 15 hours behind or ahead of a mean lunation.

The Gaulish calendar appears to have divided the year into two halves: the ' dark ' half, beginning with the month Samonios ( the October / November lunation ), and the ' light ' half, beginning with the month Giamonios ( the April / May lunation ).

There have been at least four similar reforms of the lunisolar version of the Hindu calendar, all intended to make the month a better match to the lunation and to make the year a better fit to the sidereal year.

They deduced from their measurements that the radio emission from the whole disk of the moon varied during a lunation in a roughly sinusoidal fashion ; ;

The ellipticity of the orbit also causes the duration of a half lunation to depend on where in the elliptical orbit it begins, and so affects the age of the full moon.

When keeping a running count in an accumulator then for each successive lunation you first have to subtract the full moon cycle correction for the previous lunation, then add the mean increment of 26, and then add the new full moon cycle correction.

The lunation length used in System B has also been attributed to Kidinnu.

Many Maya Long Count inscriptions contain a supplementary series, which provides information on the lunar phase, number of the current lunation in a series of six and which of the nine Lords of the Night rules.

Rudhyar defines eight lunation types: New Moon Type, Crescent Type, First Quarter Type, Gibbous Moon Type, Full Moon Type, Disseminating Type, Last Quarter Type, Balsamic Moon Type.

Converted to days and lunations < ref > 31 s / ( 86400 s / d ) / d / cy ) / ( 29. 530 ... d / lunation )< sup > 2 </ sup ></ ref >, the correction from ET to UT becomes:

So for one lunation to the next, we add 29 days, and we add 26 to the accumulator.

Some uncommon health issues that can also have an effect on English Cocker Spaniels include canine hip dysplasia, patellar lunation, canine dilated cardiomyopathy, and heart murmurs.

It varies in a period of time called a lunation, also called synodic month.

Confusingly, Gaulish Samonios ( October / November lunation ) corresponds to GIAMONIOS, the seventh month ( the April / May lunation ) and the beginning of the summer season.

Hipparchus confirmed this value for the lunation length.

And instead of computing with decimals, we approximate the lunation length by a vulgar fraction.

Here in these little rooms -- or stages arched open to the sky and river -- they choose a few lines out of the hundreds they may know and sing them according to one of the modes into which Persian music is divided.

If a work is divided into several large segments, a last-minute drawing of random numbers may determine the order of the segments for any particular performance.

that is, he is suspect, guilty, punishable, as is anyone in Mann's stories who produces illusion, and this is true even though the constant elements of the artist-nature, technique, magic, guilt and suffering, are divided in this story between Jacoby and Lautner.

This system is divided into a forest highway system, administered by the Secretary of Commerce, and a forest development road and trail system, administered by the Secretary of Agriculture.

The lower number is always divided into the upper number: Af

We divided the country into five regions plus Hawaii and Alaska and in each is included a general description of the area plus specific recommendations of places and events to cover.

Dirt, which is here defined as particulate material which is usually inorganic and is very often extremely finely divided so as to exhibit colloidal properties.

Confused and divided though this tradition may be, it is an important part of the social and cultural heritage of the group, and acts as a means of socialization, particularly for members of the rural community.

Also, the dictionary is divided into at least two parts: the list of dictionary forms and the file of information that pertains to these forms.

How to achieve this objective is a problem, but we are not divided on what we want.

This is a problem, but we are not divided over its importance or by its existence.

This is the Powell Amendment, which in 1957 divided even a `` liberal '' group like the American Veterans Committee ( AVC ).

The book is divided into chapters and in each chapter the material is grouped into Text, Tables, Illustrations, and Bibliography.
